Key Features

Early wristwatches mark the transition period from pocket watch to wrist form. Spectacular enamel dial with wide numerals and red 24-hour markings, expressive dark blue hands. The body is stout and dense . The crown is large and comfortably shaped.

According to the Omega movement serial number catalogue, the serial number on this watch dates it back to around 1915. Included is an image of a number of advertisements from 1906 – 1916, the period during which the first wristwatches came out – first for military, and then civilian use.

In 1903, the firm Dimier Frères & Cie patented the design of a watch case with brackets and a leather strap for wearing on the wrist – this is one of the first pieces of evidence for the emergence of the first wristwatch. The legendary patent received the number 9846, and the license was sold to several companies – it is this patent number that is punched on the inside of the cover of this watch – “DEPOSE No 9846”.

Pay attention to how intact the dial and case are; the case is unpolished, with a nice old grey patina from decades of careful storage.

The mechanics are in excellent condition, this timepiece is suitable for everyday wear.
