CIGA Design Central Tourbillon Everest Summit vs TAG Heuer Carrera Chronograph Tourbillon

Buy the CIGA Design if you want a distinctive, lightweight titanium watch with a central tourbillon and a dial cut from Everest rock, and you accept a niche Chinese brand with a thin service network. Buy the TAG Heuer if you want a proven Swiss chronograph-tourbillon with COSC certification, 100 m water resistance and a wide service base. The TAG is the more versatile, better-supported watch; the CIGA is the more unusual object and far lighter on the wrist.

• Choose the CIGA Design Central Tourbillon if you want a conversation-piece tourbillon in Grade 5 titanium with a stone dial and don't need chronograph functions or serious water resistance.
• Choose the TAG Heuer Carrera Chronograph Tourbillon if you want a certified Swiss movement, a working chronograph, 100 m water resistance and easy servicing.
