The quick answer.
Japan Watch Parts Genuine Casio G-Shock GD-350 Replacement Strap (10437686) is a casio replacement watch strap listed at £22.99. We recommend it for a GD-350 owner replacing a worn or damaged original strap who can confirm one of the listed caseback references.
Why it belongs on the shortlist.
The practical value here is exact compatibility. Japan Watch Parts lists this as an original Casio replacement for three GD-350 references, so buyers can restore the watch’s intended shape and fit without guessing at lug width or adapting a generic band. At £22.99, it is a focused repair part for a watch you already own.
An exact replacement for a narrow model family.
Japan Watch Parts lists part 10437686 for the Casio GD-350-1, GD-350-1B and GD-350-1C. That model-specific fit is the main reason to choose this part: it replaces the original profile without asking you to adapt a universal band.
Confirm the caseback code first.
Check the full model code printed on the back of the watch and compare it with the merchant’s compatibility list. Do not order by appearance or by the broad G-Shock name alone. If your reference is not GD-350-1, GD-350-1B or GD-350-1C, ask the seller to identify the correct Casio part.
The strap is the item being sold.
The listing describes a black resin replacement strap with a metal buckle. The watch is not included, and the page does not state that screws or other fittings are part of the package. Confirm which parts you need for the repair before ordering.

Check the full caseback code and whether you need any separate screws or fittings before placing an order.
Who it suits.
A GD-350 owner replacing a worn or damaged original strap who can confirm one of the listed caseback references.
When to choose something else.
