San Martin Watch Strap FKM Strap Rubber Strap
This San Martin Watch Strap features a premium FKM Strap design with curved ends for a secure, comfortable fit. The durable Rubber Strap is available in 19mm, 20mm, and 21mm sizes and is suitable for summer wear, diving, sports, and compatible San Martin watches including SN0144.
San Martin SN0144 FKM Curved-End Diving Watch Strap
San Martin FKM Strap is a Premium Rubber replacement Diving Strap for SN0144 watches, available in 19mm, 20mm and 21mm widths with curved ends, breathable perforations and a 316L stainless steel buckle.
Key Features
The strap is specified as fluorine FKM rubber, offering a soft, flexible construction designed for comfortable everyday and active wear.
Curved strap ends are designed to integrate closely with compatible SN0144-series watch cases for a more fitted appearance.
A 316L stainless steel buckle provides a durable metal closure that complements the sport-focused rubber strap.
Multiple perforations increase airflow around the wrist and create a sport-oriented look suited to warm-weather wear.
The strap is described as soft and comfortable, helping it conform naturally around the wrist.
The rubber construction, perforated surface and sport profile make the strap well suited to diving-watch styling and active daily wear.
Premium-Grade Fluorine Rubber Construction
This strap uses fluorine FKM rubber rather than being listed as a basic silicone band. The material is paired with a substantial 316L stainless steel buckle to create a replacement strap designed around comfort, sport styling and everyday practicality.
Choose the Correct Strap Width
Three lug-width options are available. Select the width that matches the watch case before ordering.

Important Fit & Use Notes
- Select the correct width. Choose 19mm, 20mm or 21mm according to your compatible watch case.
- Curved-end fit is model dependent. Matching lug width alone does not guarantee proper fit on every watch.
- Inspect the attachment before wear. Ensure spring bars or mounting hardware are fully seated.
- Do not force installation. If the curved end does not align naturally with the watch case, recheck compatibility.
- Check after water activities. Rinse and dry the strap and inspect the buckle and attachment points.
- Replace damaged components. Stop using the strap if the rubber, buckle or attachment hardware becomes cracked, loose or significantly worn.
