Overview

The Speedmaster is a watch that needs no introduction, first produced in 1957 and worn by numerous astronauts including Neil Armstrong and Buzz Aldrin during their lunar surface in 1969. After the Moon landing, Omega updated the case back of the Speedmaster with a new engraving to commemorate being “The first watch worn on the Moon”. The text was initially written in straight lines from 1971 to 1974, and then eventually changed to curved writing centered around a medallion. The straight writing case backs, like the one available here, are highly sought after due to their relative rarity.

Condition

UNWORN: Case is pristine with no signs of use. Original stickers may still be present. Dial, hands, and lume have no imperfections and may show natural, even aging.

MINT: Case has only a few superficial hairlines. Lugs are thick, full, and sharp with superb finishing. Dial, hands, and lume may have micro imperfections visible only with a loupe.

EXCELLENT: Case has very light scratches or nicks. Lugs are thick, full, and well-defined. Dial and hands may have imperfections visible upon close inspection. Lume is fully intact and may show slight discoloration.

VERY GOOD: Case may have a few moderate scratches or nicks. Lugs are thick and full but may have softened edges. Dial and hands may have light stains or marks. Lume may have cracks or discoloration.

GOOD: Case has many scratches and nicks. Lugs may show signs of moderate polishing with worn edges. Dial and hands may have noticeable stains or marks. Lume may be damaged or show significant discoloration.

Case: The case shows minimal signs of polishing, if any at all. The lug edges are sharp and the transition between brushed and polished surfaces is crisp. There are normal hairlines throughout and a few scratches here and there, the most notable of which are on the case back. The straight writing engraving on the case back remains deep and legible.

Dial, Hands, & Crystal: The dial itself is in excellent condition with a lovely and uniform shade of tritium with minimal degradation present on the hands. When exposed to UV light, both dial and hands briefly glow the same color and then quickly fade. The crystal is in excellent condition as well with no notable scratches and lots of life left. The etched Omega logo is present at the center.

Bracelet/Strap: The Omega 1171 bracelet, correct for this reference, is in very good condition with practically no stretching and a rather minty clasp.

Movement

Timing: The watch has been measured with a timegrapher at six different positions. The average rate, amplitude, and beat error are within acceptable ranges. While resting face up, the rate is -1s/d.

Functions: All functions including the time-setting and chronograph start/stop/reset are working as expected. It’s worth noting that the chronograph second hand resets just a hair to the left of 12 and the hour hand at 6 o’ clock resets just to the right of 12.

Service History: Unknown.
