Red, 'Sans Fil'
The height and the thickness of all 'Sans Fil' Red gaskets are identical, only the outside diamter changes. Height = 0.90mm, Thickness = 0.58mm.
These gaskets are very popular on Gucci, Longines, Omega, Tissot and many others. The gasket is often damaged at battery change. It is usually best to stretch the gasket onto the case back. Measure the rim on the case back for the internal dimension of the gasket. Measurements shown are the external diameters (1.15mm greater than the internal diameter).
Box of 30 gaskets (each size from No. 801 - No. 830). £29.95 + VAT
