Hi Froum

Here for sale something really special , this was a Covid project , at the Epoct I found locally a strange watch that have 3 pushers on a reduced speedmaster , it appears at that moment it was a test for the split second module on the valjoux 7750, at that period I decided to finish it :

Dial
Hands
Bracelet
Glass
Bezel

Also the movement got a full service done at Juval shop in La chaux de fonds after 4 years and low usage I decided use to move it to found a new project again .

Feel free to ask any question the 2 last pictures are the initial watch and what Omega put in the market.

Paul

Excellent experience with Fatcat

I just purchased a Chronostop set, complete with bracelets, box and extract. Paul was a prompt and courteous communicator. He shipped the watch quickly and I would gladly buy, sell or trade with him again. Thanks Paul!

FatCat is Great Seller!

Fellow members: Bought my first watch from the Omega Forums, a birth year Speedy. Super pleased with FatCat and how he handled everything. Fair, honest, responsive, and when I decided to buy and sent funds, he shipped the watch very quickly and it was exactly as described and in photographs. …

	Established:	1848
	Website:	https://www.omegawatches.com/
	Country of Origin:	Switzerland

Founded at La Chaux-de-Fonds, Switzerland in 1848 by 23-year-old Louis Brandt who assembled key-wound precision pocket watches from parts supplied by local craftsmen. He travelled throughout Europe selling his watches from Italy to Scandinavia by way of England, his chief market. After Louis Brandt's death in 1879, his two sons Louis-Paul and Cesar, troubled by irregular deliveries of questionable quality, abandoned the unsatisfactory assembly workshop system in favour of in-house manufacturing and total production control. Due to the greater supply of manpower, communications and energy in Bienne, the enterprise moved into a small factory in January 1880, then bought the entire building in December. Two years later the company moved into a converted spinning-factory in the Gurzelen district of Bienne, where headquarters are still situated today. Their first series-produced calibres, Labrador and Gurzelen, as well as, the famous Omega calibre of 1894, would ensure the brand's marketing success.
