The quick answer.
Japan Watch Parts Casio F-91W Replacement Strap 71604002 is a casio strap listed at £8.10 after code SEBASTIANBASSOL (before code £8.99). We recommend it for a UK-based owner of one of the listed F-91W, F-91WG, F-94WA, F-105W or F-106W references who wants a genuine Casio band.
Why it belongs on the shortlist.
This is a practical fix for a familiar Casio digital watch, not a universal strap. Japan Watch Parts identifies it as an original Casio part and lists the exact compatible references, giving buyers a clear way to check before ordering. The code lowers the part price, but delivery determines whether it is a sensible purchase outside the UK.
The part number matters more than the watch family name.
Japan Watch Parts lists specific F-91W, F-91WG, F-94WA, F-105W and F-106W references for part 71604002. Check the complete model printed on the back of your watch against that list; matching only “F-91W” in the product title is not a substitute for the exact reference.
This is a genuine Casio band, sold on its own.
The merchant identifies 71604002 as an original Casio replacement strap and states that the watch and any other parts are not included. The product page does not name the material for this exact part, so we would not assume a compound from the photograph alone.
Delivery makes the biggest difference to value.
The merchant offers free UK delivery. Its shipping policy says watch straps sent internationally use tracked and signed service at £15, before any destination taxes or duties. We would recommend the code to a UK owner or an international buyer bundling a larger parts order, not as a stand-alone US purchase.
