San Martin SN0005 GMT Watch — NH34, 40mm, Sapphire Pepsi Bezel, 200m
The San Martin SN0005 is a 40mm NH34 automatic GMT watch with a sapphire crystal red-and-blue bidirectional bezel — the Pepsi two-tone GMT bezel in sapphire rather than the ceramic or aluminium used on most watches at this price. 200m water resistance, domed bubble sapphire crystal with AR coating, five-link stainless steel bracelet with fly-adjust clasp. Available in B1 (C3 vintage green lume) and B2 (BGW9 blue lume) versions across matte black, enamel black and enamel white dial configurations.

Variants — B1 and B2
B1 Version — C3 Vintage Green Lume
Matte black dial: A flat matte black dial with vintage-style markers and C3 warm green lume. The combination of matte black, C3 green and the Pepsi bezel creates the most historically referential configuration — closest to the vintage GMT travel watch aesthetic.
Enamel white dial: A white enamel-style dial with C3 green lume and Pepsi bezel. The white dial creates maximum contrast with the red-blue bezel and the warm green lume creates a distinctive vintage palette.
B2 Version — BGW9 Blue Lume
Enamel black dial: A glossy enamel-effect black dial with BGW9 blue-white lume. The combination of enamel gloss, cool blue lume and the Pepsi bezel creates a more contemporary character than the B1 matte configuration.
Enamel white dial: White enamel dial with BGW9 blue lume — the most formally elegant and legible configuration. Applied indices on the white enamel field provide maximum contrast.
Sapphire Pepsi Bezel
The SN0005’s bezel uses a sapphire crystal insert in the red-and-blue two-tone “Pepsi” colour configuration — the same material as the bezel on the SN0151 MOP Diver and the Seestern S456 Grand GMT. Sapphire at Mohs 9 hardness resists surface scratching more effectively than ceramic and significantly more than aluminium — the bezel colour will not chip, fade or abrade under normal daily contact.
The red-and-blue Pepsi configuration is the most recognised GMT bezel colour combination — the red upper half traditionally indicates PM hours and the blue lower half indicates AM hours on the 24-hour scale, allowing at-a-glance day/night identification of the reference time zone.
Bidirectional rotation: The SN0005’s bezel rotates in both directions — unlike the unidirectional dive bezel on the SN0007-G V4 and SN0126. Bidirectional rotation allows the bezel to be used for elapsed time measurement in either direction, consistent with GMT travel watch design where east and west time zone navigation require both rotational directions.
NH34 — True GMT Hour-Jump
The NH34’s hour-jump function sets the main local time hour hand in one-hour increments without stopping the movement or disturbing the red GMT reference hand. When crossing a time zone, pull the crown to position 1 and advance the local hour hand by the number of zones crossed. The GMT hand and bezel continue to display reference time uninterrupted.
The 24-click bezel provides 15-degree increment steps — consistent with the GMT watch convention of marking each hour of the 24-hour scale.
Domed Bubble Sapphire Crystal
The bubble crystal — an exaggerated dome profile — creates the characteristic reflection ring at the bezel edge and adds the visual depth of vintage professional GMT watches. The AR coating on the dome interior reduces reflections while preserving the dome’s visual character. The “bubble” description refers to the pronounced dome height rather than the subtle curve of standard domed crystals.
C3 vs BGW9 — Which Lume Version
B1 (C3 vintage green): The warm green formulation — traditional and historically appropriate for the vintage GMT aesthetic. C3’s warm off-white ambient appearance and warm green glow complement the matte black and enamel white dial options of the B1. For buyers who want period-authentic lume character on a vintage-inspired GMT, B1 is the correct choice.
B2 (BGW9 blue): The contemporary cool blue-white formulation — brighter and more modern in character. The BGW9 on the enamel black dial creates a specific high-contrast modern aesthetic. For buyers who prioritise maximum lume brightness and contemporary character, B2 is the correct choice.

This page is generating significant search visibility but almost nobody clicks. The most likely cause is the title tag — “San Martin SN0005 Automatic Pepsi GMT Watch” doesn’t clearly communicate the sapphire bezel or 200m depth rating, both of which are the watch’s premium differentiators. The updated title “San Martin SN0005 Pepsi GMT Watch — NH34, 40mm, Sapphire Red-Blue Bezel, 200m, C3 or BGW9” communicates the specific premium specs that warrant a click from a buyer who has found several NH34 GMT options in search results.
How It Compares
vs. San Martin SN0109 Root Beer GMT — The SN0109 is 39mm at 100m with aluminium root beer bezel, gilt snowflake hands and top-hat sapphire. The SN0005 is 40mm at 200m with sapphire Pepsi bezel and bubble crystal. Choose SN0005 for deeper water resistance and sapphire bezel; choose SN0109 for the vintage root beer character and smaller case.
vs. Seestern S456 Grand GMT — The Seestern is 41mm at 200m with sapphire bezel in a different colour layout, NH34 and MOP dial option. Both have sapphire bezels at 200m with NH34 — the SN0005 has the Pepsi two-tone; the Seestern has the 24-hour GMT scale bezel in a different colour.
vs. Pagani Design PD1662 GMT — The PD1662 uses NH34 at 40mm with ceramic bezel, 100m and jubilee bracelet. The SN0005 is at 200m with sapphire Pepsi bezel — deeper water resistance and premium bezel material at a higher price.
vs. Baltany S6074 GMT — The Baltany is 39mm at 200m with ceramic pepsi bezel on jubilee bracelet. The SN0005 is 40mm at 200m with sapphire Pepsi bezel — same depth, sapphire vs ceramic bezel distinction.

Great watch, appreciate the NH34 and date window. Really like having the date window.
Great watch!
Excellent watch. Everything about the watch is great.
I first bought the black dial version and liked it so much i ordered the white dial version. Bought 2 of each. Love the watches and the historical ties to the original gmt master from the 1950's. San martin builds very fine watches, and i own quite a few.
