Variants — Four Configurations
Gun gray / bracelet: A radial brushed grey dial on steel bracelet with black ceramic bezel. The gun gray creates a utilitarian, tool-watch character — neutral grey reads as tactical and functional rather than colourful. The brushed radial finish creates subtle directional shimmer without the sunburst effect of polished dials.
Gun gray / rubber: Same gun gray dial on fluorine rubber strap — significantly lighter at 113g vs 182g. The rubber strap shifts the character from dress-sport toward active dive.
Sunray blue / bracelet: A vibrant blue sunburst dial on steel bracelet with matching blue ceramic bezel. The blue-on-blue bezel and dial combination creates a monochromatic sport character. The sunray finish shifts between bright mid-blue and deep navy at different angles.
Sunray blue / rubber: Blue dial on fluorine rubber — the most active and water-sport oriented configuration.
Logo and sterile versions are available within each colour — confirm the specific logo configuration when ordering.
C3 Green Lume
The SN007-G V4 uses C3 Super-LumiNova — the warm green formulation. In ambient light it appears as a warm off-white; in darkness it emits a bright warm green glow. C3 is the traditional dive watch lume colour associated with professional and military instruments before the introduction of modern cool-tone formulations.
This distinguishes the SN007-G V4 from the SN0017 and SN0150 which use BGW9 blue-white. For buyers who want the classic warm green lume character — the colour most associated with vintage dive watches — C3 is the correct choice. For buyers who want contemporary blue-white lume, the SN0017 with BGW9 is the San Martin alternative.
Large Rectangular Indices
The oversized rectangular luminous hour markers provide substantially more lume surface area than standard circular dots or slim baton indices. Under direct light the three-dimensional applied markers create depth and shadow. In low light and darkness the larger lume surface produces a stronger, longer-lasting glow. The prioritisation of lume volume over decorative refinement is a tool-watch design decision consistent with a watch intended for actual diving conditions.
182g on Bracelet
At 182g the SN007-G V4 on bracelet is the heaviest watch in the San Martin range reviewed here — 30g heavier than the SN0109 Root Beer GMT (151g), 49g heavier than the SN0150 MOP (133g). The 41mm case, 14mm thickness and solid steel bracelet all contribute to the weight. For buyers who specifically want a substantial, heavy-wearing dive watch, 182g delivers the wrist presence. For buyers who prefer lighter wearing, the fluorine rubber strap at 113g provides a meaningful reduction.
NH35A Movement
The NH35A is Seiko’s standard automatic with date display, hacking and hand-winding. On a 200m dive watch, hacking is the practical function — stopping the seconds for precise synchronisation before entering the water. The NH35A’s global serviceability means any watchmaker worldwide can maintain it.
How It Compares in the San Martin Range
vs. San Martin SN0017 — The SN0017 is 40mm at 200m with PT5000 or NH35 and BGW9 blue lume, enamel dial option and 11.6mm thickness. The SN007-G V4 is 41mm at 200m with NH35A and C3 green lume at 14mm. Choose SN0017 for the enamel dial and slimmer profile; choose SN007-G V4 for C3 lume and the gun gray dial option.
vs. San Martin SN008-G V3 Vintage Diver — The SN008-G V3 is 40mm at 200m with PT5000/SW200 and retro green or BGW9 lume, gold-tone vintage accents. The SN007-G V4 is 41mm with NH35A and C3 green lume, more conventional modern tool-watch character.
vs. Phylida SE-11 — The SE-11 uses Miyota 8215 at 41mm with 120-click ceramic bezel at 14.1mm. Very similar specification — the SN007-G V4’s differentiators are the C3 lume, gun gray dial option and San Martin finishing quality.
Who Is the San Martin SN007-G V4 For?
The SN007-G V4 is built for:
- C3 green lume buyers who want the warm traditional dive watch glow rather than BGW9 blue-white
- Gun gray dial buyers who want the neutral utilitarian tool-watch character not available in the SN0017 range
- NH35A buyers who want the most globally serviceable Seiko automatic on a 200m ceramic bezel diver
