Frequently asked questions
What is the lug width of the TWCO Sea Rescue Diver SRD-O?
The TWCO Sea Rescue Diver SRD-O features a lug width of 22mm. This measurement represents the distance between the two spring bars that attach the strap to the case. Always verify this dimension before purchasing a replacement strap to ensure perfect compatibility.
What is the best strap for the TWCO Sea Rescue Diver SRD-O?
There is no single "best" strap in absolute terms, but rather choices that align with your intended use. For underwater environments, a synthetic NATO offers practicality and durability. For formal daily wear, leather in calf or alligator provides sophistication. For extreme marine performance, rubber remains the most reliable choice. Your decision should reflect your relationship with the watch.
How do you change the strap on the TWCO Sea Rescue Diver SRD-O?
Changing the strap is a straightforward procedure. Position the watch face-up and locate the spring bars that run through the lugs on both sides of the case. Use a spring bar remover tool to gently push the bars inward and slide them out of their slots. Remove the old strap and insert the new strap's spring bars into the same slots, ensuring they click securely into place on both sides.
Which aftermarket straps are compatible with the TWCO Sea Rescue Diver SRD-O?
Any strap designed for a 22mm lug width is compatible with the SRD-O. This includes full-grain leather straps, alligator leather, shell cordovan, NATO straps in nylon or recycled synthetics, rubber straps, and models featuring steel deployante buckles. Compatibility depends solely on lug width, regardless of the strap manufacturer.
How long does a leather strap last on a diving watch like the SRD-O?
A quality leather strap, subjected to moderate use, will last 3–5 years before showing significant wear. However, if regularly exposed to salt water or fresh water, the lifespan reduces to 1–2 years. For a Sea Rescue Diver intended for frequent diving, it is advisable to prioritise NATO or rubber straps, which are far more resistant to moisture and marine environments.
