Similar to what we saw with the Spring Drive Diver SLGA015 and the link Spring Drive GMTs SBGE283 and SBGE285 the new Spring Drive Chronograph GMT SBGC249 and SBGC251 include a case design influenced by the new-for-2022 "Evolution 9" design codes which are intimately informed by Grand Seiko's famous 44GS case. link This new Chronograph GMT case looks like it could possibly be the most wearable Spring Drive Chronograph GMT yet even if the specs don't quite link come across that way.

While these years are sometimes debated record-keeping being what it is this is the loose link understanding among the collector community and serves as something of a warning. Should you come link across a 2597 with dual hour hands and a production date before 1961 dig as deep as you can before throwing down any cash as there is a chance the watch link was not originally made with both hour hands having been updated by a Patek retailer sometime later.
