DESCRIPTION & Specifications of the watch

MODEL: Mens IWC Schaffhausen - Custom Made Pocket Watch Conversion - Marriage watch - Antique IWC Pocket Watch Movement

In 1939 IWC was approached by two watch dealers hailing from Lisbon, Portugal Messrs Rodrigues and Teixera to be exact. Says Pantli, “But what they asked for was absolutely crazy sounding.” It’s important to understand that at the time the standard man’s wristwatch was 35 mm in diameter or smaller. Pantli continues, “They asked for a wristwatch that would have all the performance characteristics of a marine chronometer (a super accurate timepiece used for shipboard navigation) which necessitated us using our most accurate pocket watch movement the Caliber 74. What looks like a lightsabre on the front man is Mad Jack Churchill leading a beach assault with claymore in hand. Caliber 74-73 was IWC’s most accurate pocket watch movement; a natural choice for the large-cased Portuguese. It was explained to the two gentlemen that the resulting watch would be huge, almost unheard of in size at 42mm in diameter. Some how they loved this idea.” Apparently the fashion in Portugal at the time was for men to wear watches in this dimension. IWC also made its first “finger bridge” movement, Calibre 65, starting in 1893. Rather than the heavier and thicker three-quarters plate movement of that era, these movements instead had narrow bridges and cocks supporting each wheel, which allowed for a somewhat thinner and more elegant movement. In addition to a companion Calibre 66, some slight modifications lead later to the Calibres 73 and 74 finger bridge movements. These were produced from 1913 to 1931 in 67,500 examples. Additionally, a very rare and beautiful finger bridge movement was Caliber 69. At 4.7 mm in height and 16 lignes in diameter, this finger bridge Lépine movement was launched in 1898. Only about 2,100 were produced.

Not everyone has the opportunity to wear a beautiful 100 years old antique watch from a renowned brand.
