The Panerai Radiomir Composite Black Seal 3 Days Automatic takes a 26 mm strap: measure between the lugs and that is the only number you need. With a 45 mm case and 100 m of water resistance, a thicker strap balances the case. Most straps here come with quick-release spring bars, so the swap takes a minute and no tool.
