Details & Specifications
Description:
The Chronoswiss Tora Chronograph reference CH 7423 masterfully blends classical design with practical GMT and chronograph functionality, its case curving over the wrist with slender rounded screwed lugs and coin-edge detailing repeated around the lower case. The dial is crafted from hand-guilloché 925 sterling silver, featuring classic Breguet-style Arabic numerals paired with blued steel hour, minute, chronograph, and sub-dial hands.
A second time zone is displayed via a 24-hour indication with day/night function, alongside a date window, while the chronograph offers a 30-minute counter, 12-hour counter, and central chronograph seconds hand. The screwed case back is glazed on both sides, revealing the automatic Chronoswiss Calibre C.743, based on the Valjoux 7750, finished with Côtes de Genève decoration and a gold-plated central rotor. The watch is fitted with a black leather strap and a stainless steel Chronoswiss buckle.
