Frequently asked questions
What is the lug width of the TWCO Sea Rescue Diver SD?
The TWCO Sea Rescue Diver SD features 22mm lug width. This measurement represents the precise distance between the lugs protruding from the case and determines which straps you can attach to the watch. All 22mm straps in our catalogue have been verified to ensure accurate fit on this model.
Which strap do you recommend for the TWCO Sea Rescue Diver SD?
Strap selection depends on your intended use. For marine and operational environments, we recommend a NATO in synthetic materials that dries quickly and resists moisture. For formal daily use, calf leather with vegetable tanning will develop a natural patina that enhances the watch's character. Alligator remains the superior technical choice for tropical climates and humid environments.
How do you change the strap on a TWCO Sea Rescue Diver SD?
The Sea Rescue Diver SD uses a fixed lug system with lateral pins. To replace the strap, position the watch in a stable holder, locate the small holes beneath the lugs, and use a spring bar tool to gently push inward and remove the pin. Reinsert the pin into the new strap following the same procedure in reverse.
Are aftermarket straps compatible with the TWCO Sea Rescue Diver SD?
Yes, any strap with 22mm lug width is compatible with the Sea Rescue Diver SD. Our catalogue offers options in leather (calf, alligator, shell cordovan), NATO fabric, and vulcanised rubber. Compatibility is guaranteed by the standardised lug width; each product has been tested to ensure coupling without vertical or lateral play.
How long does a leather strap last on a TWCO Sea Rescue Diver SD?
Leather strap durability depends on material and environment. Calf leather with vegetable tanning lasts approximately 18-24 months in daily use, developing desirable patina. Alligator, thanks to its natural scales, resists 24-36 months in humid environments. Shell cordovan can exceed 3 years with optimal seasonal maintenance. In saline environments, durability reduces by 20-30% compared to standard values.
