I have a 38.5mm Omega Aqua Terra with 19mm lugs. I prefer straps to bracelets, but I would like to be able to swim with it. It is, after all, water resistant to 150m, but I don't because it has a leather strap. I've looked for 19mm rubber straps to use when I'm hanging out at the pool or swimming, but they seem to come in even sizes. One vendor recommended buying a 20mm strap and just letting the rubber compress. I'm not sure if this is just a vendor trying to sell product or if this is what people really do. Is there perhaps a hidden source for odd size rubber straps?
Any advice appreciated.
