The Panerai Radiomir Perpetual Calendar GMT Goldtech takes a 27 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. Automatic movement. Most straps here come with quick-release spring bars, so the swap takes a minute and no tool.
