Details
This watch case back wrench was designed to open RLX Oyster cases. The six tempered rings will fit the most existing size of the RLX Oyster cases, and because they are precision-made to interlock with this particular watch case type, they will not slip and mar the surface of the watch. This cheap watch opener comes complete with six dies with the measurements of 29.50mm + 28.30mm + 26.50mm + 22.50mm + 20.20mm and 18.50mm.
