For sale or trade is a rather attractive 1954 stainless steel date-at-6 Seamaster Calendar with yellow gold arrowhead markers. The original dial has developed a nice, even patina. The 2757 reference case is in very nice condition and appears to be unpolished. The 355 bumper movement runs, winds, and sets well, but the service history is unknown so a service is recommended prior to regular use. Additional details are below, and feel free to reach out with any questions. Dial: Original dial has developed a nice, even patina and features the desirable arrowhead markers in yellow gold. Yellow gold markers and hands are in nice condition. Radium lume is intact and has developed a nice, consistent color. "Swiss Made" is present below the 6 marker as expected. There are small marks on the dial here and there but none take away from the even patina. Case: Original 34.5mm 2757-3 reference case is in nice, unpolished condition. Bevels on the lugs are still very sharp, and "Seamaster" is visible on the small bevel on the case back. There are small scratches and marks here and there but none are significant. The most noticeable scratch is on the case back where it says "Seamaster". Crown: Crown is signed with the Omega logo, but I do not believe it to be the correct style. I believe it should have a clover crown, possibly a bowler hat crown although those were used mostly on the earlier date-at-6 references. Crystal: Generic crystal with some small scratches that should buff out. Movement: 355 bumper caliber movement has some discoloration and scratches near the stem. Watch runs, winds, and sets well. Calendar functions as expected. Service history is unknown so a service is recommended prior to use. Serial number dates the watch to 1954. Strap: Comes with a generic brown leather strap and a steel buckle (not the strap or BOR pictured). This watch looks incredible on a 5-row BOR, and I have a spare one for additional cost if the buyer is interested. Price is $700 (reduced from $900). Open to trades for non-radium 50s or early 60s Seamasters/Constellations/Conquests/Flagships (see my WTB/WTT here). I'll cover insured US shipping, international shipping to be discussed with buyer.
