At a guess I'd say the 220g range on bracelet but they have a much better feel on bracelet as the mass of the bracelet balances out the weight of the head and stops it sliding from side to side on your wrist.
A few of the guys in Bienne were wearing these on bracelets. They really looked sharp, tremendous wrist presence. 👍
I agree it looks sharp but I still remember my former PO XL which was pretty heavy.
Still in my opinion PO GMT Goodplanet with orange GMT hand looks better than the blue Titanium version.
