Originally launched in 2019 link with a 43mm white gold case 2021 saw a titanium follow-up of the same size and now we have a 40mm option in red gold or titanium both of which are limited to 20 pieces. The new case also houses a new movement the HMC 904 vs. the 903 link in the 43mm versions which like its forebearer is a hand-wound link movement with 90 hours of power reserve a rate of 3 Hz and is hand-finished and beautifully decorated.

These are going to be some fast sellers. I think link the SBGW231 is so popular because it's a manifesto of sorts. It's link a watch clearly made for enthusiasts from its discreet size and hand-wound movement to its dateless design and affordable price tag. With its diamond hand-polished hands link and dial furniture it's something like the platonic ideal of a Grand Seiko watch.
