The Oris TT1 Chronograph Stainless Steel - Ceramic / Black / Bracelet takes a 25 mm strap: measure between the lugs and that is the only number you need. A chronograph carries a bit of sport: perforated leather, rubber or a sailcloth strap all sit well. 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.
