Omega Speedmaster Professional
Reference: 3572.50
Serial # 44,356,xxx (1979 - 1982 date range)
Caliber: 863 (18 jewel)
Aesthetic Condition: The tritium hour markers on the dial have aged to a beautiful amber hue. Some scratches on Hesalite. Scuff on the lower left lug, other than that, the case is in good condition for it’s age. As can be expected for a 40+ year old Speedy that's been carefully worn and enjoyed, there are minor signs of wear on the watch, all of which are captured in the pictures below.
Mechanical Condition: The movement appears to be healthy, running +1 / sec per day with an amplitude of 281 degrees in the dial up position. The chronograph functions (start, stop, and reset to "0") are all in good working order. The crown winds buttery smooth.
Bracelet: 1499/642 (this reference has a nice taper down and is much more comfortable than the subsequent style that lacks any taper down and has the chunky push button clasp)
Fitment: will fit up to an 7 inch wrist. Addl links can be ordered for larger wrist sizes
Box & Card: No box, no cards included.
Price: $3,750
Shipping: $45 for fully insured 2-day delivery to your local FedEx facility in the USA
Form of Payment: bank wire or Zelle from US or Canadian based buyers only
My Location: Arizona, USA
Returns: No returns. Please carefully review the photos that I have posted here to make sure you are comfortable with the condition of the watch.
