A Handsome, Fortis B42 Official Cosmonauts Automatic Chronograph, in Superb Preowned Condition and Supplied with Box and Original Purchase Receipt.

Founded by Walter Vogt in Grenchen, Switzerland, in 1912, the Fortis watch company first began to make watchmaking history 12 years later when it set up production with John Harwood, inventor of the automatic wristwatch. The patented Harwood Automatic was released by Fortis in 1926, becoming the world’s first automatic watch in series production. Maintaining a strong reputation for functional and reliable watches in the following years, Fortis also launched the world’s first waterproof watches in 1943.

What’s On Offer

This Fortis B42 is in fantastic pre-owned condition with barely a mark on the case and certainly nothing to speak of on the dial. A meaty watch at 42mm, this watch not only looks the part, but it also has plenty of functionality including chronograph, tachymeter, day, date, hour, minute, and second functions.

At the heart of this timepiece is ETA-Valjoux Caliber 7750. The Automatic movement operates at 28800 A/h and keeps the hands revolving smoothly and accurately for precise, reliable timekeeping. It contains 25 jewels and picks up all the advantages of this high-performance ‘engine’, including a 44-hour power reserve.

The black dial with the corresponding uni-directional rotating bezel in black looks great with the brilliant white Arabic numerals and sword hands, and a punch of colour on the zesty orange central seconds. A fantastic watch at a great price, complete with its original box, booklet, Roscosmos certificate and original purchase receipt, but the original warranty car from Fortis has been misplaced!
