The GA-2100 Builds Gallery Is Live

Sixty seconds, one watch, a full transformation — that is the idea behind the new GA-2100 builds gallery. Seventeen real mods filmed start to finish: steel, titanium, carbon, frosted, offshore-style, transparent. Every build links to the exact parts, so “I want that one” is one click from a cart.

Pair it with the reference shelf that grew alongside it: the lug width chart (every model, one table), the adapter guide (who needs what), the spring bar guide (the 1.8mm vs 2.5mm trap), and the water resistance guide (what is safe to change).

New builds land in the gallery as they are filmed — the queue includes titanium and carbon walkthroughs. Watch one, then go build one.
