Omega 17J Seamaster grade 354 wrist watch, case #2635-8SC, vintage mechanical manual-wind rose gold-flashed nickel movement with bold red ruby jewels and a brushed finish, this movement had significant damage to the automatic wind rotor barrel so we have rebuilt the movement to convert it to a manual wind, champagne-toned metal dial with fancy raised silver Arabic numbers and chevron style markers, luminous markers and a black-marked minute register has notable spots of discoloration and patina across the surface, silver steel wedge style hands with luminous inserts and a silver sweep second hand, none of the luminous material is retaining or emitting light.
Heavy stainless steel (SS) round water-resistant case with a gently sloped bezel supporting a slightly domed plastic crystal, an Omega marked crown and flared curved extended lugs, case is showing normal even wear with some smoothing to the Omega symbol on the crown, some small but notable nicks & scratches on the frame and back and a few short scratches in the crystal, measures approx. 33mm in diameter x 41mm lug to lug x 10mm thick (crystal included), new black padded nylon band. A workhorse Omega from the mid-1900s that, despite the signs of age and use, is running strong and will make a perfect watch to wear daily, in good overall condition!

This watch is in good running condition, unless otherwise noted in the description. This means that on receipt, pending any item-specific running conditions noted in the description, you can expect the watch to be winding and setting properly and to run smoothly while keeping reasonable time. We consider "reasonable time" to meet these basic guidelines:
- Railroad Grade Watches will be keeping +/- 5 minutes per day
- Pocket and Wrist Watches with 15 or more jewels will be keeping +/- 10 minutes per day
- All key wind watches and watches with 14 or fewer jewels will be keeping +/- 15 minutes per day
The above guideline is the lowest standard in which we would ship out a watch, however in most cases, you will see much better timekeeping. Most of our watches have been in storage for many years, so if you plan on carrying/wearing them everyday, you should consider having them cleaned and oiled soon, and then once a year thereafter to keep them in top running condition. If the watches will be for occasional use or display, they should be cleaned and serviced every 3 to 5 years depending on use.
As of February 5th, 2026, we are not offering a cleaning and service option through PM Time Service. While we do hope to offer this again in the future, we are unfortunately unable to meet customer requests for watch servicing at this time. Please note that, unless otherwise mentioned within the "Full Description" tab, this watch is being sold in good running condition and is ready to wear or carry on arrival.
Unlike modern quartz watches, most vintage watches need daily winding in order to keep the watch functioning for timekeeping. Additionally, there are a number of different ways to set the time other than simply pulling the crown away from the watch body. We are happy to provide an overview of each of the different setting types on our
"How To Use" page, where we also provide information on proper winding techniques for each style and some suggestions for the proper long term care and storage of your watch.
For your gift giving convenience, please find a consolidated overview of the information on this item, with no reference to the price, on this
printer-optimized page.
