Variants — Four Configurations
Light blue / logo: A turquoise-blue dial with applied San Martin hexagonal logo. The light blue creates a bright, contemporary character — the combination of blue dial with snowflake hands and 3D applied markers is visually clean and immediately legible.
Light blue / sterile: Same light blue dial without brand text — the clean anonymous dial for buyers who prefer no logo.
Black / logo: A classic black dial with applied logo. Maximum contrast — black field with BGW9 blue-white lume markers creates exceptional low-light readability.
Black / sterile: Black dial, no logo. The most minimal configuration — the sterile black dial with snowflake hands references the anonymous professional instrument aesthetic.
SN021-G-B2 vs SN021-G — Key Differences
Both are 37mm San Martin automatics at 100m with PT5000/SW200 choice. The differences:
| Feature | SN021-G | SN021-G-B2 |
|---|---|---|
| Crystal | Standard dome sapphire | Top-hat dome sapphire |
| Hands | Curved carved | Snowflake |
| Markers | Standard applied | 3D applied |
| Date | Check model | None |
| Thickness | 11mm | 11.3mm |
| Dial options | 5 variants (inc. cursive) | 4 variants (inc. sterile) |
| Lug width | 20mm | 19mm (most versions) |
Choose SN021-G for the cursive or printed logo dial options and the 20mm standard lug width.
Choose SN021-G-B2 for the snowflake hands, top-hat dome sapphire and the light blue dial option.
Snowflake Hands
The snowflake hour hand — a wide, faceted hand with a cross-shaped profile at the tip — maximises lume surface area while creating a distinctive and instantly recognisable silhouette. The snowflake is associated with specific vintage sports watch design references from the 1960s and 1970s. On a clean no-date dial with 3D applied markers, the snowflake hands are the primary visual identity of the B2 compared to the standard SN021-G.
Top-Hat Sapphire Crystal
The top-hat crystal has a flat top with steep curved sides — the profile creates the characteristic edge reflection ring of vintage professional watches and adds visible dome height above the bezel. The AR coating maintains clarity under direct light. At 11.3mm total case thickness with the top-hat dome, the B2 is 0.3mm thicker than the standard SN021-G — the dome adds the visual character while the overall profile remains slim.
No-Date Symmetrical Dial
The absence of a date window preserves the dial’s circular symmetry — all twelve hour positions carry markers of consistent size without any aperture interrupting the layout at 3 o’clock. For buyers who prefer the clean uninterrupted dial character of no-date watches, the B2 is the correct San Martin 37mm recommendation. The SN021-G’s date display status should be confirmed from its product page.
Applied 3D Markers
The three-dimensional applied hour markers are physically elevated above the dial surface — metal marker housings create micro-shadows at their base edges and catch ambient light along their face. The 3D markers add perceived dial depth beyond what printed markers achieve, consistent with the visual depth created by the top-hat dome above them.
Who Is the San Martin SN021-G-B2 For?
The B2 is built for:
- Light blue dial buyers who want the distinctive turquoise-blue colour in a compact 37mm automatic
- Snowflake hand buyers who want the distinctive vintage hand profile on a clean no-date sports watch
- No-date symmetrical dial preference buyers who want the clean uninterrupted hour layout
- 37mm compact buyers who also want the top-hat dome crystal’s vintage profile
How It Compares
vs. San Martin SN021-G — The sibling 37mm automatic. See comparison table above — choose by hands, crystal and dial colour preference.
vs. San Martin SN008-G V3 — The SN008-G is 40mm at 200m with vintage gold-tone accents. The B2 is 37mm at 100m with clean BGW9 lume — more compact and contemporary in character.
vs. Hruodland F029 — Both compact automatics at 36–37mm. The F029 is a 200m diver with NH38 and both bracelet and NATO included. The B2 is 100m with PT5000/SW200 and the top-hat dome crystal.

Top picks just for you
This is my first San Martin and I’m impressed with the quality for the price.
My first San Martin watch and what a beauty it is. the pictures just don't do this watch justice. Very impressed with the spec and attention to detail, and great communication with the seller.
Beautiful watch, the finishes are incredible for this price range! To see how the watch evolves over time.
Excellent watch! I’ve been wearing it daily since I received it. I went with printed Hex logo to match printed markers. Had one bad screw but I needed to remove a few links anyway. Watch would be perfect if the clasp had one more micro-adjust and a flip-link for a sweaty-day extension. If they make some glossy bright colored dials I’d buy more of this 36mm model. Exhibition case-back might help shave 0.5mm-1mm off the thickness.
The watch arrived on time. I just received it today so I haven't had any any time with it. First impressions are very nice. Fit and finish, first class. I don't think anyone would be disappointed with the way it looks.
Fantastic watch fast postage, ordered the San Martin print dial and perfect service as always
A very attractive watch an accurate as well.
