The quick answer.
Japan Watch Parts Casio W-71, W-86 Replacement Strap 71603087 / 71604153 is a casio strap listed at £10.76 after code SEBASTIANBASSOL (before code £11.95). We recommend it for a UK owner of one of the listed W-71 or W-86 references who wants a genuine Casio replacement band at a low price.
Why it belongs on the shortlist.
The W-71 and W-86 are long-running, inexpensive Casio digitals, and a worn resin strap is the first thing to fail. Japan Watch Parts sells the original Casio part and lists the exact references it fits, so the check is simple: read the model code on your caseback and match it. The code trims the price, and UK delivery is free.
Match the reference on your caseback to the list.
Japan Watch Parts lists W-71-1VD, W-71-1VS, W-71-1VSCG, W-71-1VSD, W-71-1VX, W-71MV-1VS, W-71MV-1VSD, W-86-1VQ, W-86-1VR and W-86-4VSD. The model number is printed on the back of the watch. If yours is on the list, this is the part to order; a similar-looking Casio digital is not a substitute for an exact match.
A genuine band, sold on its own.
The seller identifies it as an original Casio replacement strap and says it comes with no other part or accessory. The part is also supplied as 71604153, which is why the listing carries both numbers. Reuse your existing spring bars or buy matching ones separately.
The code makes a small saving, delivery decides the value.
