Omega ‘Worldtime’ my heart skips a beat seeing such a magical instrument. I couldn’t think of a better watch for the holidays, although you might just want to escape or forget about the time altogether and enjoy the peace and quiet to a full. However, it is kinda fun to see all the time differences at a glance. Worldtime models are rare to come by.
The Omega watch company was founded in 1848 by Louis Brandt in La Chaux-de-Fonds. In 1880, they moved to its current location in Bienne, Switzerland. Surprisingly it took them 46 years to make the Omega name official.
Not only does the watch date from 1923, so does the movement. The Swiss Omega 40.6L T1 manual wind caliber was used until 1936, and in those 13 years a whooping ‘one million’ where produced. This says something significant about the incredible quality, reliability and durability of this stunning movement with Geneva striping. The porcelain dial is created with worldwide city names, plus the time corrections. Beginning at the 12 o’clock with Stockholm in red letters. The question arises whether these pocket watches where specifically for the Swedish market, as they all seem to begin with Stockholm. The fine watch hands are crafted in rose gold, in a Spade & Whip model. The dial is in stunning condition, the only barely noticeable thing I could find are two insignificant fleabites, one under Moskau, and the other after New York, only visible with a magnifying glass. The case measures 5 cm and is created in 800 silver - Grouse hallmarked on the cuvette and case cover. The only not silver part is the bow, as this needs to be a slightly more heavy-duty material to carry the weight of the pocket watch. The crystal is original and made of glass with a faceted rim and ever so slightly domed towards the middle. It’s still early days, but if you are going on a vacation or just relaxing around the house, whatever the case, why not have something within reach that makes pastime a bit more enjoyable, besides a little sunshine ☼
Oops! I almost forgot to mention ‘Erik’ the engraving at the back, bottom of the case. Does anyone know who Erik is?
