From newest to oldest they are:

1. SBGP017 in 2022, the ‘Shinshu Sea of Clouds’ for the 55th anniversary of the 44GS case; with 9F85 and display back

3. Change to SBGE253/255/257

What say you?
P.S.: Will not consider those big GS GMTs in the 44mm size, as I have decided to keep things small! SBGE283/SBGE285, both are out of my…
