San Martin Automatic Watch Snowflake Hands Sports Watch
This San Martin 36mm Automatic Watch features distinctive Snowflake Hands and a refined Explore Series design for versatile everyday styling.

San Martin SN021-G-B2 36mm Automatic Explorer Watch
Compact proportions, snowflake-style luminous hands and a clean numberless dial give the San Martin SN021-G-B2 a purposeful sports-watch character. Built around a seller-listed 316L solid stainless-steel case, sapphire crystal and automatic mechanical movement options, this model combines traditional watchmaking with a streamlined everyday design.
Compact Mechanical Styling with a Clean Explorer Influence
The SN021-G-B2 is designed around balanced proportions and a straightforward dial layout. The listing identifies it as a 36mm BB36 Explorer Series sports watch, while the structured specification gives a dial-diameter category of 35–39mm.
Its visual identity comes from a numberless dial, large luminous markers and distinctive snowflake hands. Depending on the selected variation, the seller lists light blue and black dial options.
Under the sapphire crystal, the watch is offered with automatic mechanical movement options including PT5000, ST2130 and SW200. The exact movement therefore depends on the variation chosen at checkout.
Key Features of the San Martin SN021-G-B2
316L Solid Stainless-Steel Case
The detailed specification identifies the case as 316L solid stainless steel, paired with a matching stainless-steel bracelet for a cohesive all-metal profile.
Sapphire Crystal
Sapphire crystal is listed for the dial window, providing a premium transparent surface over the numberless dial and luminous handset.
Automatic Mechanical Movement
The watch is self-winding and offered with seller-listed PT5000, ST2130 or SW200 automatic movement configurations.
Snowflake Hand Set
Broad snowflake-style hands create the signature dial appearance while providing a large surface for luminous material.
BGW-9 Blue Lume
The seller specifies BGW-9 blue luminous material on the hands and hour markers to support visibility in darker surroundings.
Fine-Adjustment Folding Clasp
The listed folding clasp includes a safety mechanism, San Martin 3D hexagonal logo and four-position fine-tuning functionality.
Automatic Movement Options for Different Variations
The supplied listing title highlights a PT5000 automatic mechanical movement, while the detailed specification identifies the movement choices as PT5000 / ST2130 / SW200.
Because the product page displays more than one movement option, buyers should verify the selected variation before ordering. The screenshot also shows separate selection buttons labeled PT-ST and SW200.
All of the listed choices are described by the seller as automatic mechanical movements, meaning the watch uses mechanical operation rather than a battery-powered quartz movement.
Minimal Markers, Snowflake Hands and Blue Lume
Numberless Explorer Layout
The specification lists the display type as numberless. Large geometric hour markers provide the principal reference points without crowding the dial with printed numerals.
BGW-9 Blue Light
BGW-9 luminous material is listed for both the hands and hour markers, producing the cool blue appearance shown in the supplied product imagery.
Two Listed Dial Colors
The specification names Light Blue Dial and Black Dial. Availability may depend on the current seller variation selection.
Compact Dimensions for a Balanced Wrist Profile
The SN021-G-B2 is presented by the seller as a 36mm-class watch. Its detailed specification lists an 11.3mm case thickness and 45.5mm lug-to-lug measurement, while the dial-diameter category is stated as 35–39mm.
Seller-Listed 10Bar Water Resistance
The product specification gives a 10Bar water-resistance rating. The watch is also tagged with the seller feature term “DIVER.”
A seller-listed pressure rating should not automatically be treated as certification for professional or deep diving. Water-resistance performance can depend on crown position, seals, maintenance, temperature changes and use conditions. Follow the manufacturer’s instructions for water exposure.

Stainless-Steel Bracelet with Fine Adjustment
The watch is paired with a stainless-steel bracelet and a folding safety clasp. According to the detailed seller specification, the clasp incorporates a 3D hexagonal San Martin logo and a four-position fine-tuning function.
Fine adjustment can help refine the bracelet fit without changing the overall appearance of the watch. Proper sizing may still require bracelet-link adjustment depending on wrist circumference.
Mechanical Watch Care
- Keep the crown properly secured before exposure to moisture.
- Avoid strong impacts even though the watch is designed as a sports-oriented mechanical timepiece.
- Keep the watch away from unusually strong magnetic sources where practical.
- Mechanical watches may require periodic professional servicing for long-term performance.
- Do not attempt to open the case without appropriate watch service tools and experience.
Bracelet & Exterior Care
- Wipe the stainless-steel surfaces with a soft microfiber cloth after regular wear.
- Remove dirt from bracelet gaps gently rather than using harsh abrasive cleaners.
- Avoid chemicals that may affect seals, finishes or luminous components.
- Inspect the clasp and bracelet connection points periodically.
- Rinse only according to the manufacturer’s water-care guidance and dry the watch thoroughly afterward.
Traditional Mechanical Design in a Compact Sports Format
The appeal of the SN021-G-B2 comes from its relatively restrained design. Instead of relying on a highly complicated dial, it uses bold luminous markers, distinctive snowflake hands and a clean numberless layout to create its identity.
A sapphire crystal, seller-listed 316L solid stainless-steel case, automatic movement choices and BGW-9 lume add substance to that minimalist appearance. The light blue variation introduces a brighter visual character, while the black dial keeps the design more traditional and understated.
For buyers comparing compact automatic sports watches, the SN021-G-B2 combines a 36mm-class profile with mechanical movement choices and a stainless-steel bracelet in a straightforward Explorer-inspired package.
