29er Big GMT — Black Dial / Black Pigskin

On black pigskin, the 29er Big GMT is the closest the family comes to a business watch. The second time zone is there when you need it and invisible when you don't, and Mühle-Glashütte keeps the flange scale grey so it never competes with the hours.

Sailing gave the 29er its name: the dinghy class that leads crews to the Olympic 49er. Mühle launched the line in 2006 and added this GMT in 2026, using the same 42.4 mm case in a slimmer 10.3 mm form with a longer-running caliber.

The black dial carries applied indices coated with Super-LumiNova, a date at 6 o'clock, and a blue-tipped 24-hour hand reading the grey rehaut. The steel case has anti-reflective sapphire, a screw-down crown, an exhibition caseback and 10 bar of water resistance; the black pigskin strap is 22 mm at the lugs. The automatic SW 330-2, Version Mühle holds 56 hours, hacks its seconds and is regulated in Glashütte to run between zero and eight seconds fast a day.

For anyone who keeps two clocks in their head and would rather not keep two watches.

Perfect for: business travel watches, black leather GMT automatics, dual time zone dress-sport watches.
