Longiness Dolce Vita watches
For the perceptive aficionado, the modified hairspring cannot be neglected from the list of developments. The previously flat spring has been replaced with a cylindrical one. A world first for wristwatches! Originally it was invented by John Arnold in 1782. The man duly remarked that he cannot foresee his invention being used in smaller timepieces as its spatial requirements are extensive. The modern age’s miniaturization techniques however have made this still amazing feat possible. The unfinished springs are supplied by Lange & Söhne Uhren – both companies being Richemont SA subsidiaries this is of no surprise – and then JLC’s watchmakers create the curve and through a week’s hard work, finely tune each and every example. As a consequence of added ‘useful’ weight, the moment of inertia had been increased from 10mg•cm2 to 12.5 mg•cm2, as a final effort for even better rate results.
Recently Breitling unveiled the modern Transocean collection with a three-hand and chronograph model which I reviewed hands-on here. The Transocean is a slick, retro-looking boardroom watch in a contemporary size, fitting for today's "Breitling guy." That means the three-hand automatic isn't dainty being 43mm wide. This new Transocean Unitime however is larger at 46mm wide. That certainly isn't too large for a Breitling, but is probably close to the size ceiling for what people want in a classic looking timepiece.
Below you can see a picture of the original 1970s Montecarlo chronograph that the new Heritage Chrono Blue was based on. By the way, that particular piece was sold via an Antiquorum auction for over ,000. The new and old pieces from a design perspective are extremely similar, though differences exist. One of the most important differences is the size, as the Heritage Chrono Blue is 42mm wide in a polished and satin finished steel case (the original is smaller).
