Dubey & Schaldenbrand Spiral - Split-Second

"Spiral - Split-Second" is … as its name suggests … a split-second chronograph which features the patented blued-steel "Isoval" spiral recoil spring between the chronograph counter hand and the split second counter hand. Although without function, this purely decorative spiral pivots around the center axis of the hands.
"Spiral - Split-Second" comes in a 316 L stainless surgical steel case measuring 40 x 46 mm with a thickness of 14.7 mm. It uses a curved sapphire crystal which features an anti-reflective coating on both sides of the crystal for added legibility. As for all watches of the "Spiral" family, the unique and stylish "mobile lugs" conveniently fix the leather strap to the case. The silvered dial with its stunning guilloche pattern along with the roman numeral hour markers give this model a "face" which will certainly not go unnoticed.
For this particular model, the performance of the split second chronograph is at its absolute peak thanks to its self-winding, automatic movement which runs on a frequency of 28,800 oscillations. A close look at the dial reveals 4 sub-dials namely … a 30-minute counter … a 12-hour counter … a small-second counter and … a date indicator.
Typical of Dubey & Schaldenbrand watches, the sapphire crystal case back allows one to appreciate the beauty and functionality of the hand-engraved movement.
