Monaco LS & 24 - 3 mm clasps

The TAG Heuer Monaco is an automatic chronograph wristwatch originally introduced by Heuer in 1969 to commemorate the Monaco Grand Prix. Originally badged as Heuer Monaco, it was notable for being the first automatic chronograph, as well as the first with a square case. The Monaco has become synonymous with Hollywood film star Steve McQueen, who wore one in the 1971 film Le Mans. The Monaco Calibre 360 LS (Linear Second) was unveiled in 2006. Unlike typical chronographs, it lacks a stopwatch dial. The watch features a 1/100th chronograph counter exterior to the chronograph engine and a linear second indicator at 3 o’clock using an exclusive hairspring technology. Introduced in 2009, the CAL5110 Monaco 24 pays homage to the 24 Hours of Le Mans. It bears the distinctive Gulf Oil stripes, and its Calibre 36 movement is encased within a steel-tube housing visible through the dial face. The watch case is machined from industrial-grade tungsten.
