Greubel Forsey ←
Double Balancier Convexe
This is one that I really don’t want to take off my wrist. I’ve had the pleasure of wearing almost everything, and nothing is as comfortable as these Sport Greubel Forsey watches. The two balance wheels are a feast for the eyes and a brilliant chronometric invention. These are made in small numbers (22/year for 3 years, so 66 total), sell at full retail, and have rarely been seen on the pre-owned market.
I have a brand new titanium bracelet as well for it that is available at extra charge
