Synchron Ti300M Sealab (Limited Edition)

Synchron is a Swiss dive-watch brand whose watches are serialised and hand-assembled in Switzerland, and the Ti300M Sealab is a limited edition of 500 of its titanium diver with an orange dial. The case, caseback and bezel are all Grade 5 titanium, and the case is slimmer than earlier Synchrons at 11.9 mm while keeping the same 41 mm diameter and dial. It is 45 mm lug to lug, rated to 300 m, and weighs only 50 g on its Tropic rubber strap. The bezel is 120-click unidirectional with a US Navy no-decompression dive table, and the dial uses applied markers with X1 Super-LumiNova. Inside is a Swiss La Joux-Perret G100 in Soigné grade, adjusted in four positions, with 68 hours of reserve.
