Key Features

FKM Fluorine FKM Rubber

The strap is specified as fluorine FKM rubber, offering a soft, flexible construction designed for comfortable everyday and active wear.

Curved-End Profile

Curved strap ends are designed to integrate closely with compatible SN0144-series watch cases for a more fitted appearance.

316 316L Stainless Steel Buckle

A 316L stainless steel buckle provides a durable metal closure that complements the sport-focused rubber strap.

••• Ventilated Hole Design

Multiple perforations increase airflow around the wrist and create a sport-oriented look suited to warm-weather wear.

Soft & Flexible Feel

The strap is described as soft and comfortable, helping it conform naturally around the wrist.

Diving-Oriented Design

The rubber construction, perforated surface and sport profile make the strap well suited to diving-watch styling and active daily wear.

FKM

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.

19mm Curved-end strap option
20mm Curved-end strap option
21mm Curved-end strap option
Fit check: Strap width must match the watch’s lug width and compatible curved-end case profile. Do not choose by wrist size alone.

Made for Active & Warm-Weather Wear

Summer Comfort

Perforated sections encourage airflow around the wrist, making the design particularly suitable for warmer conditions.

Diving Watch Styling

The broad rubber profile pairs naturally with sport and diving watch cases.

Everyday Use

Flexible FKM construction provides a practical alternative to a metal bracelet for regular casual wear.

Sweat-Friendly Design

Ventilation holes reduce the amount of continuous material resting directly against the wrist during warm conditions.

Sport Appearance

Textured surfaces and perforated detailing give the strap a performance-focused visual character.

Style Refresh

Changing strap colors offers a simple way to refresh the look of a compatible San Martin watch.

Compatibility

The strap is specified for the San Martin SN0144 Series and is available in 19mm, 20mm and 21mm widths. Because the strap uses shaped curved ends, compatibility involves more than simply matching the lug width.

Before ordering: Confirm the watch model, lug width and curved-end shape. A strap with the correct width may still not sit properly on an unrelated watch case if its lug geometry is different.

Care & Maintenance

  • Rinse the strap with clean fresh water after exposure to sweat, salt water or chlorinated water.
  • Dry the strap thoroughly before prolonged storage.
  • Clean with mild soap and water when needed.
  • Avoid harsh solvents, bleach and aggressive chemical cleaners.
  • Use a soft cloth on the 316L stainless steel buckle.
  • Check the buckle, spring bars and attachment points periodically.
  • Do not stretch the strap excessively during installation.
  • Make sure both curved ends are properly seated before wearing the watch.
  • Allow the strap to dry before storing it in a closed watch box.

Packing List

Watch not included: This product is a replacement watch strap. The watch case shown in styling examples is not part of the strap purchase unless specifically included in the selected offer.

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.
Product Disclaimer: Fit depends on watch model, lug width, curved-end geometry and installation hardware. The specifications list a 20cm band length and also provide separate strap-section measurements of 80mm + 125mm excluding the buckle; small measurement differences can occur depending on the measuring method. Color appearance may vary with lighting and display settings. References to diving or waterproof use describe the strap’s intended sport application and do not determine the water-resistance rating of the watch itself. Always follow the water-resistance specification of the watch case.
