Description
A Vintage Omega Seamaster Cosmic, produced in 1969. This day-date model features both the day and date at the 6 o’clock position, with the weekdays displayed in English. The dial has a beautiful dusted effect that comes alive under certain light angles and remains in perfect condition.
The case measures 35 mm excluding the crown and retains most of its original polish. The original plexiglass has a small scratch near the edge at the 4 o’clock position. It is almost invisible during daily wear, but replacement can be arranged if the buyer prefers, we leave that decision up to you.
Inside is the automatic caliber 752 movement, serviced in February 2026, currently running and functioning great. The watch is paired with a brown calf leather strap, which suits the piece very well. Overall condition is very good, making this an excellent daily wearer or elegant dress 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.
