The Longines Heritage Twenty-Four Hours Single Push-Piece Chronograph 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 47.5 mm case, a thicker strap balances the case. Most straps here come with quick-release spring bars, so the swap takes a minute and no tool.
