SLGA021 lake suwa is 176gr. Your FF is proper heavy. On the other hand when I tried the new 42mm FF in titanium ( with strap mind you! ) I was surprised of its heft, couple days ago I had tried the Omega NTTD titanium on titanium mesh bracelet and it was lighter than air, so I was expecting a light watch, however it totally was not, not in a bad way though…
