For sale or trade is a very clean and original Dennison cased stainless steel Omega with unique all-arabic numerals and a manual wind, sub-second 266 caliber movement. Comes with it's original coffin box, which is in very nice condition. The dial has some minor debris, but it presents well. The movement runs, winds, and sets well, but service history is unknown so as usual I recommend a service prior to regular use. Additional details are below, and feel free to reach out with any questions. Dial: Original, non-refinished, dial is in nice condition. There are some light specks of debris on the dial, particularly on the top half, but it is still quite attractive. Features unique and attractive all-arabic numerals. "Swiss Made" text is present below the 6 marker as expected. Case: Original 34mm 13322 reference Dennison-made stainless steel case appears to be unpolished and is in very nice condition. Original brushing is still present on the sides of the case and on the case back. Dennison cases were produced in the UK, which is where I sourced the watch from. You can read more about the Dennison company in the article linked to from this very helpful resource: omega-constellation-collectors.blogspot.com. Crown: Original crown is in nice condition. Crystal: Crystal was recently replaced as the original was chipped. Original will be included in the sale. Movement: Original 266 caliber manual wind movement runs, winds, and sets well. Service history is unknown, so as always I recommend a service prior to regular use. Serial number dates the watch to 1955. Strap/buckle: Comes on the generic black leather strap pictured (not the brown one). Box: Comes with it's original 1950s "coffin" style box. The box is in very nice condition with no noteworthy scratches or discoloration. Both the small buckle on the inside for securing the watch and the buckle for closing the box function as expected. Price is $900. Open to trades for non-radium 50s or early 60s Seamasters, Constellations, Geneves, Conquests, and Flagships (see my WTB/WTT here).
