Watch Specifications
silvern screw-down pushers
Screw-down pushers grant an additional mechanical aspect to watches. In order to operate the stopwatch function, one has to first unscrew the collar then, close it again after stopping it. The crown is always decorated with an M.Chrono – the darker the brighter
Superluminova is a phosphorescent phosphor and free of radioactive additives. Superluminova is a hundred times brighter than other inactive luminescent pigments. When the luminescent pigments have been excited by daylight or artificial light, they release the absorbed light energy over several hours in the dark. This gives the watch extremely good clarity even in the dark.Silver Chrono , screw-down pushers, caseback
Our display back case uses a blue anti-reflective sapphire crystal and thus allows for an unobstructed view of the pulsating caliber. One has the feeling that the soul of the mechanical automatic movement can both be felt and seen. The watch is alive. Together with the possibility of the custom labelled rotor, each watch becomes a truly personal gift – even to oneself.ETA 7750 Movement
After the takeover by ETA, the Valjoux 7750 was re-named the caliber ETA 7750. This is quite possibly the most successful automatic chronograph movement of all time. The caliber stands out due to its high degree of accuracy and robustness. It has 25 stones, a ball-bearing mounted rotor, and a uni-directional winding mechanism. The 7750 has a 1/8-second counter, a 30-minute counter, a 12-hour counter, 28,800 half oscillations per minute and a power reserve of ca. 44 hours. The loss of accuracy is 1-6 seconds per day. Movement revisions are recommended every 3 to 8 yearsTOP Execution

Steel
Not all steels are created equal. We use 316L stainless steel; one of the hardest premium steels in the world. In addition to its hardness and resistance, this high-quality steel stands out because of its finish as well as its very fine silver hue. 316L steel has a significantly lower nickel emission than, for instance, 904L steel, which is also a high-strength steel alloy. This is, for us, a reason to favor 316L stainless steel.1

Modern
Our success is built on these watches! They are our classics, and may forever be called "Chrono Modern". Designed by Daniel Dreifuss, the 051015 dial gives both watch and owner a subtle dynamism. The dimensions of these watches and their clear edges leave no doubt - a "Chrono Modern" always adorns a strong arm. No matter whether on water, on land or in the air. Mechanically driven, of course, the "Chrono Modern" is modular in design and allows for unique customization. You will love it as it will love you.
It is an absolute honor to be associated with Les Clefs d’Or and create a special edition chronograph in collaboration with our ‘neighbors’ Luc Frieseisen, President of the Les Clefs d’Or Suisse and Concierce at The Dolder Grand Zurich

The Maurice de Mauriac L3 Les Clefs d’Or is no ordinary timepiece. A see- through caseback allows a glimpse of the automatic movement with personalized rotor featuring the Les Clefs d’Or insignia plus the name & membership number of each concierge individually engraved. Members can use chronograph functions to time various activities associated with their role. Its balanced proportions provide optimal wearability for any type of wrist and the rich gradient blue hue on the dial is truly mesmerizing, promoting an excellent contrast to the golden hands/indexes and case. Avaible in stainless steel or stainless steel with an gold PVD coating.

Based on the L3 Spheric Blue tricompax chronograph with fumé blue dial and housed either in an unprecedented stainless steel case with gold PVD coating, the L3 Les Clefs d’Or features the minimalistic outlook authored by award-winning Basel designer Fabian Schwaerzler — and is highlighted by the golden crossed keys in the hour register at 6 o’clock. Symbolically, the iconic logo also represents the access key to the watch: only Les Clefs d’Or associates are eligible to get one.
« The specific color combination we chose is no coincidence. It’s true that, in some European countries, the expression ‘blue over gold’ means something is perfect. But, most of all, blue and gold are Les Clefs d’Or corporate colors», says Leonard Dreifuss, Maurice de Mauriac’s Creative Director

THE GOLDEN WATCH FOR LES CLEFS D’OR 🔑💛
From Zurich to New York, Paris to Tokyo and everywhere in between, no one knows the world like Les Clefs d’Or. Founded in 1952, the prestigious organization partnered with us to create its own official timepiece. Noblesse oblige!
These concierges are only found in first-class five-star hotels and can be recognised by the crossed keys on their revers. Until now. From now on, these insiders will be increasingly recognisable by their exclusive watch - the Maurice de Mauriac L3 Les Clefs d’Or. This watch is exclusively reserved for members of Les Clefs d’Or.
