I bought this last month from another user on watchex, but I just don't wear it enough. It's a really cool watch just doesn't match my style as much as i had hoped. I had a new battery put in it since I got it. I copied most of the previous listing below. **Omega Seamaster from 1973** Ref: 198.001 **little learning** (from web): The tuning fork watch is like no other battery driven watch, or mechanical for that matter: it is driven by a tuning fork vibrating at 300-720 times a second, depending on the model; as a result, it doesn’t tick, but hummms. The index mechanism also means the tuning fork watches are characterised by a constant swe-eping seconds hand.This movement is licensed by ESA to Bulova. Omega as a caliber 1250, the base move-ment is an ESA (Ebauches S.A) 9162 found in several other watches from Baume et Mer-cier, Eterna (1550), Cerina (29-151), IWC (150), Longines (6312), Tissot (2010), Zenith (50.0) etc.Conditon is good, case and glass are great. I can point out that there is some dial discoloration when you look at it on room light from some angles. On outside light I cant make photo of it. Case is steel 36.5mm without crown in good condition. Normal signs of wear. **Crown is signed** Dial is nice **blue colored vertical brushed dial** Glass is signed with **omega logo** Movement works as need to Strap and buckle are new. leather strap pictures from original listing: [https://imgur.com/a/svzYnZD](https://imgur.com/a/svzYnZD) Price: **$525** paypal (FF or G&S +5%) shipped to CONUS.
