TOURBILLON CALIBER

Invented by French horologist Abraham-Louis Breguet in 1795, the tourbillon is an advanced regulating organ present in certain high-end mechanical watches, intended to improve the precision of timepieces. It consists of a rotating cage containing the balance wheel and its hairspring, the escape wheel, the lever and the second wheel which drives it. The cage rotates 360 degrees every 60 seconds, which counteracts the effects of gravity and reduces any positional errors of accuracy. The tourbillon embodies watchmaking know-how, only a few Manufactures master the creation of this caliber masterpiece.

TOOL WATCH REVOLUTION: LUXURY MEETS FUNCTIONALITY

" The Yachtingraf Tourbillon Maréographe has been designed for purpose, a true tool watch able to withstand the harshest conditions. It features a double dome sapphire crystal, a unidirectional count-up sapphire bezel, 10 ATM water-resistance, high anti-magnetic resistance (2,000 Gauss) and shock-resistance (5,000G) as well as an innovative tide indication complication animated by an exceptional and precise tourbillon caliber offering over 4 days power reserve.

This unique set of features is uncommon since tourbillon watches are mostly designed as watchmaking art pieces that are delicate in their utilization. This is one of the rarest tourbillons built for daily use, a luxury timepiece that is as rugged and functional as it is beautiful and refined, a tool watch in the lineage of YEMA watches. "
