Very rare Omega Speedmaster Professional Quartz Ref. 186.0004 LCD Chronograph “moonwatch-case” wristwatch, made circa 1977.  Fine and unusual, water-resistant, quartz wristwatch with LCD digital display with chronograph functions, light, date, day of the week on an integral stainless steel Omega bracelet. Runs great and all functions work as expected, light function works as well. Please take a look at the photos for the condition.

Only produced for 18 months during 1977-78.  In 1979 it was submitted to NASA for testing under the Alaska IV project name. The cal. 1620, developed by Omega and SSIH (later to become SMH). Although it has only basic functions by today’s standards, it is neverthless still a very accurate watch, capable of 0.15 seconds per day, or 5 seconds per month. This is better than a lot of quartz watches available even now. The very good accuracy is due to the high quality quartz resonator used, manufactured in-house by SSIH.

Two-body, polished and brushed, lyre lugs, push-buttons for the chronograph and light functions on the right, the one at 10 is for mode selection, case back embossed with the Seamaster logo, mineral crystal.
