This Milus Tirion TriRetrograde Seconds Skeleton 18kt Rose Gold Special Edition has a mechanical automatic self-winding MILUS 3838 triple retrograde movement. It's rhodium-plated, with fausses cotes embellishment. It's constructed with 29 jewels, a shock absorber device, and a straight-line lever escapement. It includes a monometallic balance that's adjusted to heat, cold, isochronism and 5 positions, a self-compensating flat balance spring, and a rotor oscillating weight with ceramic ball bearings. The mechanism oscillates at a frequency of 28,800 vph. The strong, imposing round case in 18kt Rose Gold forms the perfect framework for the creative core elements of the dial. It is built up of two layers: the movement base is covered by genuine carbon fibre and the second level consists of a plate in the same high-tech material. Here, dynamically placed and easily readable, are the Arabic hour numerals and indices. Positioned at 4 o’clock, the large date is displayed to its full advantage. The heart of the dial and the watch is formed by the round inner skeleton area. This is where the three seconds-display sectors with the eye-catching and stunning second hands in the shape of an oscillating rotor are placed. Positioned in three separate circle segments at 6, 10 and 2 o’clock, they work in ‘flying relay’ clockwise. Starting at 6 o’clock, the first hand in the shape of an oscillating rotor performs its spectacular 20 seconds ride and swings instantly back to the right to its starting position. Going clockwise, the next seconds hand at 10 o’clock followed by the third at 2 o’clock accomplish the same journey. This alternation tirelessly repeats itself, giving the overall impression of a magic and fascinating dance portrayed by these outstandingly shaped seconds hands. Superlative technology lays bare its secrets: the dial of the TIRION TriRetrograde Seconds Skeleton 18kt Rose Gold displays the unique precision of the watch, allowing an exclusive look at the inner life of the automatic movement through the opening at its centre. Lovers of consummate craftsmanship will be captivated. And this timepiece shows off its talents at the back of the case too, in that the round convex sapphire crystal window offers a view of the movement.
