For the creation of the first mechanical self-winding chronograph, the SIO – Italian School of Watchmaking, part of the LOCMAN group, was partnered by DePa Swiss Movements, an enterprise of Swiss artisans specialised in movement concept and development.
The SIO – Italian School of Watchmaking was founded by Locman in 2006 with the intention of establishing a research centre and constant monitoring the quality of their watches. Over the years, SIO has certified and also developed the mechanisms of its major collections, partnering with companies for special projects.
The oscillating weight is enhanced with a bright yellow shade and personalised with the LOCMAN ITALY logo. The calibre reference – SIO/DPch 88 – is indicated on the movement mainplate.
After upgrading the Montecristo’s movement, the SIO engineers went one step further and also revisited the design, giving it some extra competitive edge. The dial features sunray-pattern enamelling, the minute counter is placed at 3 o’clock and the small seconds subdial at 9 o’clock, while the tachometric scale – absent in the quartz version – appears around the inner bezel ring of this model.
The AISI 316L steel and titanium case is made of exclusively non-allergenic materials usually found in surgical instruments, and is topped by a flat glass with a special sapphire treatment to give the material a hardness comparable to that of natural sapphire as well as an exponential increase in its transparency. Tested water resistant to 10 atmospheres, the Montecristo Crono case is attached to the silicon or hi-tech Lorica strap by the distinctive triple-bar lugs.
