The Forgotten Rolex Brands You’ve Probably Never Heard Of

Before Rolex, there was Wilsdorf & Davis

To understand these obscure names, we first need to go back to London in 1905.

That year, Hans Wilsdorf founded a watch distribution business with Alfred Davis. The company became known as Wilsdorf & Davis, often shortened to W&D.

At the time, the wristwatch was still far from the dominant format it would later become. Pocket watches remained the norm, and wristwatches were often considered less serious instruments. Wilsdorf thought differently.

He believed a wristwatch could be elegant, convenient and, crucially, accurate. Wilsdorf & Davis sourced movements from Switzerland and sold watches in Britain. Rolex itself confirms that Wilsdorf was already working with small, precise Swiss movements during this period.

Then came the name that changed everything.

The Rolex name appears in 1908

Hans Wilsdorf registered Rolex as a trademark in 1908.

Why Rolex?

There are countless theories surrounding the origin of the word, but Wilsdorf wanted something short, distinctive and easy to pronounce in different languages. Just as importantly, it needed to fit neatly onto a watch dial. It worked rather well.

But the Rolex name did not immediately replace every other name connected with Wilsdorf's business. Quite the opposite. During the following decades, Wilsdorf experimented with numerous trademarks and watch brands alongside Rolex.

And this is where things become interesting.

Were they really Rolex “sub-brands”?

Not exactly. The term Rolex sub-brand is convenient, but historically it can be misleading.

These names covered several different arrangements. Some were alternative brands associated with Wilsdorf's businesses. Others were trademarks used for more affordable watches. Some appeared in particular markets or distribution channels.

So finding an old watch with one of these names on the dial does not automatically mean you've found a secret vintage Rolex. That distinction matters enormously for collectors.

With early twentieth-century watches, the dial, movement and case may carry different signatures. Watches were frequently assembled using components sourced from specialist manufacturers, while retailers and distributors could also have their names placed prominently on watches.

Authentication therefore requires considerably more than recognising one familiar stamp inside a case. With that established, let's meet the forgotten names.

Marconi: one of Wilsdorf's earliest alternative brands

One of the best-known forgotten Wilsdorf names is Marconi. The Marconi trademark appeared in the early 1910s, at a time when Rolex itself was still developing its identity.

Marconi watches occupied a different part of the market from many Rolex-branded pieces. Rather than relying exclusively on the movements associated with early Rolex watches, Marconi examples could use movements from other Swiss suppliers.

Today, surviving Marconi watches appear in numerous configurations, including both wristwatches and pocket watches. And that creates an important collector warning.

Is a Marconi watch a Rolex?

Not in the way a vintage Submariner, Datejust or Oyster is a Rolex.

Some genuine period Marconi watches can show connections to Wilsdorf's businesses through markings, cases or other components. But putting “Rolex Marconi” into a sales listing can easily imply more than the watch itself proves.

For collectors, provenance matters more than the headline. Case markings, movement architecture, hallmarks, dial originality and period-correct components all need to tell the same story.

A mysterious name alone doesn't turn an old watch into a hidden Rolex treasure.

Unicorn: the affordable alternative that disappeared

Yes, Rolex history genuinely includes a brand called Unicorn.

Wilsdorf registered names including Unicorn Lever around the end of the 1910s, followed by further use of the Unicorn name in the early 1920s.

The idea was broadly familiar: offer dependable watches at prices below the core Rolex product. There was one rather obvious branding problem. Unicorn imagery and terminology were already used elsewhere in the watch trade. That made the identity far less distinctive than Rolex.

And if there was one thing Hans Wilsdorf understood exceptionally well, it was the value of a recognisable name. The Unicorn connection was ultimately discontinued, leaving behind watches that today occupy a curious corner of Rolex-related collecting.

They're unusual, historically interesting and relatively unknown.

They are also an area where buyers should research carefully, because not every watch carrying the Unicorn name dates from, or has a connection to, Wilsdorf's business.

Rolco: perhaps the most obviously Rolex-inspired name

If Rolco sounds suspiciously like Rolex, that's because subtlety wasn't exactly the objective. Rolco was another name used in Wilsdorf's attempts to offer watches below the main Rolex level. Period material shows Rolco appearing alongside other lower-priced alternatives, making its relationship to Wilsdorf's broader strategy particularly interesting.

From today's perspective, Rolco provides a glimpse into a question that luxury companies still wrestle with:

How do you reach a broader audience without weakening your premium brand?

Wilsdorf tried answering that question repeatedly.

Marconi was one attempt. Unicorn was another. Rolco was another. And eventually, Tudor would provide the answer.

Rolwatco: an acronym hiding in plain sight

Things become even more wonderfully obscure with Rolwatco.

The name is generally interpreted as a contraction of:

ROLex WATch COmpany.

Catchy? Perhaps not. Interesting to collectors? Absolutely.

Rolwatco appears on some early watches and components from the Wilsdorf orbit and is another reminder that the clean corporate structure we associate with Rolex today developed over time.

Early watchmaking was considerably messier.

Brands, case makers, movement manufacturers, retailers, importers and distributors could all leave their signatures on a watch. That makes watches from this period fascinating, but also difficult to authenticate.

Oyster Watch Co.: when a technology became part of the identity

Another name occasionally encountered in discussions of forgotten Rolex-related brands is Oyster Watch Co. This one is particularly interesting because the word Oyster would become absolutely fundamental to Rolex itself.

In 1926, Rolex introduced its famous waterproof Oyster wristwatch. The Oyster case became one of the foundations on which the modern Rolex identity was built.

Instead of disappearing into a secondary brand, Oyster became something much more valuable: a recognisable technology and product family attached directly to Rolex.

That was arguably a stronger proposition. Rather than making cheaper brands look vaguely like Rolex, Rolex itself was becoming more distinctive.

Water resistance, chronometric performance, automatic winding and eventually professional sports watches would give customers reasons to specifically want the name on the dial.

Solar Aqua: the Canadian connection

One of the stranger chapters in this story takes us across the Atlantic.

Solar Aqua watches were sold in Canada through Eaton's, the department-store empire that once occupied a huge position in Canadian retail.

Vintage examples associated with the arrangement can show connections to Rolex production through their cases and internal markings while carrying Solar Aqua rather than Rolex prominently on the dial.

It was effectively a very different strategy from creating another globally recognised Rolex alternative. Instead, the watches were closely connected to a powerful retailer and a specific market.

For vintage collectors today, Solar Aqua watches are interesting precisely because they don't fit neatly into modern ideas of what a watch brand should be.

A buyer once entering Eaton's wasn't necessarily shopping for the same type of luxury object that someone buying a modern Rolex GMT-Master II is purchasing today.

The watch industry, and Rolex with it, was still evolving.

Then Hans Wilsdorf created Tudor

Eventually, Wilsdorf found the formula that his earlier experiments had failed to perfect.

Tudor. The Tudor trademark was registered on Wilsdorf's behalf in 1926. Wilsdorf took ownership of the brand in 1936, and in 1946 he established Montres Tudor S.A.

His objective was remarkably clear. Wilsdorf wanted watches that could be sold for less than Rolex while retaining the dependability for which Rolex had become known.

The crucial difference was that Tudor wasn't merely an anonymous cheaper Rolex.

It was allowed to build an identity. Rolex initially stood behind Tudor's technical characteristics, distribution and after-sales support. Early Tudor watches could use Rolex-associated components and Oyster cases, strengthening the relationship between the two names.

But Tudor gradually became recognisable in its own right.

That was the breakthrough.

Why Tudor survived when Marconi, Unicorn and Rolco didn't

The early Wilsdorf brands largely solved a price problem. Tudor solved a positioning problem. That distinction is everything.

A cheaper watch carrying echoes of Rolex risks making customers wonder why they should spend more for Rolex. A separate brand with its own identity gives customers another reason to buy.

Over time, Tudor developed its own design language, history and reputation for robust tool watches. The Tudor Oyster and later Oyster Prince helped establish that character during the post-war period.

Eventually came famous Tudor Submariners, military associations, chronographs and, decades later, the Black Bay and Pelagos families. Modern Tudor is therefore not simply “Rolex for less.”

And that is precisely why the brand succeeded.

Is Tudor still owned by Rolex?

Rolex and Tudor remain closely related through their shared ownership structure and Hans Wilsdorf heritage, but they operate as distinct watch brands.

Modern Tudor increasingly stands on its own product strategy, movements, designs, ambassadors and collections.

That distinction also matters on the secondary market.

Someone searching for a Tudor Black Bay isn't necessarily looking for a substitute for a Rolex Submariner. And someone buying a vintage Tudor Submariner may specifically want the unusual combination of Tudor branding and historical Rolex-associated architecture found in those watches.

The relationship adds interest. It doesn't erase Tudor's identity.

Are forgotten Rolex brands collectible?

Absolutely, but this is specialist territory. A Marconi, Unicorn or Rolco can make for a far more unusual conversation piece than another familiar vintage Rolex reference.

Rarity, however, shouldn't be confused with value. An obscure watch isn't automatically expensive simply because very few people have heard of it.

For early Wilsdorf-associated watches, condition and originality matter, but documentation can matter even more.

Before buying one, look carefully at:

• Dial originality: Has the dial been refinished or had Rolex added later?
• Movement markings: Do they correspond with known period examples?
• Case signatures and hallmarks: These can help establish who made or imported the case.
• Serial or reference numbers: Are they consistent with the claimed period?
• Movement and case compatibility: Do the components actually belong together?
• Provenance: Old invoices, advertisements or family history can be extremely useful.
• Seller terminology: “Rolex-related” and “Rolex” are not interchangeable descriptions.

This is a part of the vintage market where buying the story instead of buying the watch can become expensive.

Beware of “Rolex-signed” vintage watches

The popularity of Rolex creates an obvious incentive to make obscure vintage watches appear more closely related to the brand than they really are. A Rolex signature can be added to a dial. A movement can be placed into a different case. A genuine period case can be paired with a movement that never originally belonged inside it.

And a legitimate historical connection with Wilsdorf can be exaggerated into “rare early Rolex.”

Collectors should therefore be particularly cautious when an obscure watch suddenly becomes much more valuable because of one Rolex marking. The entire watch needs to make historical sense.

When it doesn't, the crown on the dial may be the least trustworthy part of it.

The forgotten brands explain modern Rolex better than you might think

Today, Rolex appears almost impossibly consistent. The crown. The Oyster case. The Perpetual rotor. A tightly controlled model range. An unmistakable visual identity.

But that consistency was learned.

Marconi, Unicorn, Rolco, Rolwatco and the other names associated with Wilsdorf's early business show an entrepreneur experimenting with branding, pricing and distribution. Some ideas disappeared. Others evolved. And eventually two exceptionally powerful identities emerged.

Rolex became the flagship. Tudor became the distinct alternative.

The forgotten brands sitting between them are more than historical trivia. They show how Hans Wilsdorf learned one of the most important lessons in the luxury watch industry:

A successful second brand needs more than a lower price. It needs a reason to exist. More than a century later, Rolex and Tudor are proof that he eventually found one.

Frequently asked questions

What were Rolex's forgotten brands?

Names historically associated with Hans Wilsdorf and his watch businesses include Marconi, Unicorn, Rolco, Rolwatco and several other trademarks and commercial lines. Their exact relationship with Rolex differed, so describing every one of them as a conventional modern “sub-brand” is an oversimplification.

Was Marconi made by Rolex?

Marconi was connected to Hans Wilsdorf's watch business, but Marconi watches should not automatically be treated as Rolex watches. Individual examples need to be assessed through their case, movement, markings and provenance.

Did Rolex make Unicorn watches?

The Unicorn name was used within Hans Wilsdorf's early watch activities, including registrations such as Unicorn Lever. However, the Unicorn name was also used elsewhere in watchmaking, making careful authentication essential.

What is a Rolco watch?

Rolco was one of the alternative watch names associated with Wilsdorf during Rolex's early history and was positioned below the core Rolex offering.

What does Rolwatco mean?

Rolwatco is generally understood as an abbreviation of “Rolex Watch Company” and can be found on some early watches or components associated with Wilsdorf's business.

Was Tudor created by Rolex?

Tudor was created under Hans Wilsdorf's direction as a separate watch brand that could offer reliable watches at a more accessible price than Rolex. The Tudor trademark dates to 1926, while Montres Tudor S.A. was formally established by Wilsdorf in 1946.

Is Tudor a cheaper Rolex?

Historically, Tudor was designed to offer reliability associated with Rolex at a lower price. Modern Tudor, however, operates with its own collections, design identity and watchmaking strategy, so simply calling it a cheaper Rolex misses much of what the brand has become.
