The San Martin SN0129-G6 GMT pairs a striking gradient desert-texture dial with the practical Japan NH34 automatic GMT movement. Available in Gradient Purple and Gradient Green, each dial uses a deep color transition and textured surface that changes character with the light.
The compact 39mm 316L stainless steel case is topped with sapphire crystal and a fixed 24-hour GMT bezel, while a dedicated GMT hand allows a second time zone to be tracked alongside local time. A solid stainless steel bracelet with San Martin’s fly-adjustable clasp completes the versatile travel-watch design.

The dial is the defining feature of the SN0129-G6.
The Gradient Purple version transitions through rich violet tones inspired by an evening sunset, while the Gradient Green version uses deeper emerald shades inspired by the colors of the aurora.
A textured surface adds depth beneath the applied indices, 3D San Martin logo and contrasting GMT hand, giving both versions a more dimensional appearance than a conventional flat dial.
The Japan NH34 mechanical movement adds a dedicated 24-hour GMT hand for tracking an additional time zone.
The movement operates at 21,600 vibrations per hour, uses 24 jewels and provides approximately 41 hours of power reserve. The date window at 3 o’clock keeps everyday information immediately visible without overcrowding the dial.
At 39mm, the SN0129-G6 offers relatively compact proportions for an automatic GMT watch. The crown guards increase the overall case width around the crown while preserving a balanced profile on the wrist.
The solid 316L stainless steel bracelet combines polished center links with brushed outer surfaces and tapers toward the clasp. The fly-adjustable clasp allows quick fine adjustment without removing bracelet links.
