Description
For sale is a rare and highly functional timepiece from Fortis – the B-42 Diver Chronograph Alarm. This professional diver’s watch combines the practicality of a chronograph with a mechanical alarm feature, a unique combination that is hard to find in sport watches today.
The watch boasts a robust 42 mm stainless steel case, a sturdy presence on the wrist, and excellent legibility. It features a rotating dive bezel, chronograph functions, and the rare mechanical alarm complication—a true collector’s gem. This model is extremely scarce on the secondary market and rarely available for purchase.
The watch comes as a full set, including the original box, papers, and warranty card. It also underwent a complete professional service recently, ensuring it is ready to wear without any additional expenses.
Condition is very good—worn but well cared for, with no major signs of use.

I am very pleased with the way the people at Wristler work. Fast and clear communication (also after the sale). A reliable club that deliver what they promise. And not unimportant; I bought a beautiful watch.

I recently bought my Rolex Datejust through Wristler. The whole proces was supereasy, Whristler answered a couple of question that I had fast. Payment went securely through them. The watch is magnificent!! Couldn’t be happier with the watch, but also the the whole buying process.
