Accurate to one-fifth of a secondPreview SIHH 2018: The 1815 CHRONOGRAPH in pink gold
The 1815 CHRONOGRAPH is the perfect choice for purists in search of a technically flawless stopwatch that is reduced to the quintessential functions. The slender chronograph sweep seconds hand is activated with a pusher at 2 o'clock. It indicates the time with a resolution of one-fifth of a second.
The flyback function allows instant consecutive measurements: when the pusher at 4 o'clock is pressed, the chronograph's seconds- and minute-counter hands jump to zero and then immediately restart to take a new measurement.
The peripheral pulsometer scale is reminiscent of a classic pocket watch function; it is used for heart rate measurements. This measures the time it takes to count 30 heartbeats. On the scale graduated from 40 to 200 beats, the chronograph sweep seconds hand indicates the heart rate in beats per minute.
Arabic numerals and the railway-track minute scale are hallmarks of the 1815 watch family that has combined classic design and mechanical ingenuity with optimised functionality since 1995. The symmetrically arranged subsidiary dials for the minute counter at 4 o'clock and the subsidiary seconds dial at 8 o'clock emphasise the balanced character of the timepiece. Two solid-gold push pieces with defined trigger points control the chronograph including the flyback function.
With the two new versions, watch connoisseurs are spoilt for choice: Featuring a black dial, hands that match the pink-gold case and a black alligator leather strap, the 1815 CHRONOGRAPH has a harmoniously sculpted and distinctive silhouette. Thanks to the expressive combination of an argenté dial, blued-steel hands and a red-brown alligator strap, it is a functional understatement.
The manually wound calibre L951.5 movement has a power reserve of 60 hours and a freely oscillating balance spring paired with a cam-poised balance. The sapphire-crystal caseback reveals salient hallmarks of the lavishly finished chronograph movement. Among other things, it exposes the column wheel that controls the chronograph functions, the levers of the flyback mechanism and the snail of the precisely jumping minute counter. The hand-engraved balance cock also complements the typical quality features of this watch.
