I have here an Omega thin arrow RAF 1953 watch. Original radium dial. Watch is running strong. Case is in great condition. Dial has some marks as shown but overall looks attractive to me and the lume has a warm patina. I included pictures of the caseback, dust cover, movement, and close ups of the lugs. Comes with an extract from the archives showing it was issued to the UK. AJTT mentions that only 5,900 pieces were made, that the same basic design was relaunched in 1957 as the "Railmaster," and that there are some interesting antimagnetic faraday cage type features such as an extra thick dial of 1 mm compared to the standard of 0.4 mm with the dial and dust cover being made of "mumetal," a nickel iron alloy. As you might know, the thin arrow was recalled for radiation and most of these were redialed by the MOD as the "fat arrow" tritium variant. Few of the original thin arrow dials survived, here's your chance to get one.

	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.
