NATO strap for Smart Watch

Why a two-piece NATO for smart watches?

The classic NATO strap threads under the case as a single piece. That is its advantage on a mechanical watch. But on a smart watch — Apple Watch, Garmin, Samsung Galaxy Watch — the optical sensors on the back of the case need direct, constant contact with the skin to work correctly. A strap that passes under the case creates an extra layer that disrupts the reading.

The two-piece NATO solves this. Each half attaches to its own spring bar without threading under the case. The sensors stay against the skin. The smart watch works fully.

A nylon strap for sport and water

Nylon is the ideal material for a smart watch worn during sport. Water-resistant, perspiration-resistant, it dries quickly and does not retain odour. Machine washable at 30°, it recovers its shape and colour after every wash. Marine-grade anti-corrosion stainless steel buckle and keepers complete that resistance — ideal for swimming, running, cycling and all water sports.

Everyday nylon comfort

Nylon is softer and lighter than a rubber strap. It does not stick to the skin during exercise and does not deform in heat. For a watch worn from morning to night, in sport and at the desk, it is a natural choice.

Compatible with most smart watches

This two-piece NATO strap fits smart watches equipped with standard spring bars. Check the lug width of your watch before ordering — it is usually listed in the manufacturer specifications.

Frequently asked questions

Why not use a classic NATO on a smart watch?

The classic NATO threads under the case as a single piece, creating a layer between the sensors and the skin. This disrupts heart rate and other optical sensor readings. The two-piece NATO avoids this by keeping the case back in direct contact with the skin.

Is this strap suitable for swimming?

Yes. The nylon is water-resistant and dries quickly. The marine-grade stainless buckle resists seawater and chlorine. Machine washable at 30° after pool use.

What width should I choose for my smart watch?

Check the lug width in your watch specifications. For Garmin, Samsung and others, measure the gap between the attachment points. The right size ensures a secure fit and full sensor contact.
