Is there a consensus as to the 'best' spring bars for use in a vintage Rolex Submariner with drilled lugs? I'm keen to get a few spares given I'm now regularly changing straps.
20mm springbars with shoulders will be easiest to change. Get them at least 1.8mm thick. Plenty of sources out their from Ottoe Frei, to eBay, to OEM from your local dealer.
