Daytona-Style Seiko Mod

The TONA MOD collection brings together independent Seiko mod watches in a Daytona-style chronograph layout. Listed VK63 options are battery-powered and add a separate stopwatch function, rather than an automatic mechanical movement. TONA MOD – PANDA and Ice Blue – Gulf NATO present different models; the latter lists an Ice Blue dial and NATO strap. The TONA MOD with a black dial and decorative hour markers is also available with an automatic NH35 movement. In this version, the chronograph pushers and subdials are decorative and have no stopwatch function.

Choose a chronograph by the listed variant

A Panda layout, a dark dial or a coloured version can change the way the same chronograph idea reads on the wrist. PANDA and Arctic Racer each pair a 40 mm case and sapphire crystal with an Oyster bracelet. Ice Blue – Gulf NATO instead pairs an Ice Blue dial with a NATO strap.

VK63 rather than automatic

A VK63 listing points to a battery-powered Meca-Quartz chronograph with a stopwatch function. The VK63 guide explains that direction; the NH35 guide is the relevant comparison for an automatic movement without that stopwatch function.
