Frequently asked questions

What is the lug width of the TWCO Sea Rescue Diver SRD-Y?

The lug width of the TWCO Sea Rescue Diver SRD-Y is 22mm. This measurement refers to the internal distance between the lugs where the strap is secured to the case. All straps with a 22mm lug width are compatible with this model, offering extensive choice across different materials and styles.

Which strap would you recommend for the TWCO Sea Rescue Diver SRD-Y?

The ideal strap depends on your intended use. For regular marine operations, a technical NATO fabric strap is recommended for durability and rapid drying. If you prefer elegance combined with functionality, a vegetable-tanned calf leather strap is excellent. For intensive saltwater environments, gummed rubber ensures zero maintenance and superior chemical resistance.

How do I change the strap on the TWCO Sea Rescue Diver SRD-Y?

To change the strap, remove the spring bars retaining the original strap to the case lugs using a dedicated spring bar tool. Insert the new spring bars into the holes of the new strap, then anchor them to the lugs until they click into place. Ensure the pins are securely fastened before wearing the watch.

Can I use an aftermarket strap on the TWCO Sea Rescue Diver SRD-Y?

Yes, any strap with a 22mm lug width is perfectly compatible. Aftermarket straps offer advantages in aesthetic customisation and specialised materials. Ensure the lug width is correctly measured (22mm internal) to avoid improper fitting or misalignment.

How long does a leather strap last on the TWCO Sea Rescue Diver SRD-Y?

A vegetable-tanned leather strap typically lasts 2-4 years with daily wear, increasing to 5-7 years with occasional use. The natural patina improves over time, creating a unique finish. Avoid prolonged exposure to saltwater humidity, which accelerates ageing. In intensive marine environments, prefer rubber or fabric NATO straps.
