Watch case-back gaskets for specification-led selection. Compare the required profile, dimensions and material with the individual watch before choosing a replacement.
Choosing a watch gasket
Identify the required fitting
Record the watch or case reference and the specified gasket profile. Confirm whether a diameter is internal or external, then check thickness and material. A broad size range alone does not establish a fit.
Read the assortment details
For a mixed pack, check the individual sizes and quantities supplied. The current assortment lists 100 flat rubber gaskets and a 14–30mm range; diameter basis, thickness, rubber compound and quantities by size require confirmation.
Resolve the missing detail
Contact JTR with the product code and required measurements before ordering when the listing does not establish suitability. A gasket purchase or replacement does not establish a watch’s water resistance; follow the relevant service and testing requirements.
