EXTRACT OF ARCHIVES
39.583.xxx is a very nice example of the reference ST 186.0004 from February 1979, originally delivered in Belgium.
It is fitted with the caliber 1620 (as indicated on the disk wearing also the serial number), and with its original and conform stainless steel Omega bracelet.
It is in overall very good condition. The batteries have been changed recently, and it works perfectly.
It is provided with the original user manual and also a nice and very rare brochure from this period presenting the complete generation of quartz Speedmaster models.
About the model
In the second half of the 1970s, Omega embarked on the quartz revolution and even decided to fit some Speedmaster models with the LCD calibre 1620 quartz movement.
In 1977, Omega unveiled the Speedmaster Professional LCD, reference ST 186.0004. The display window has the following functions: time (12 or 24 hours), date/day, and chronograph. In addition, pressing the central pusher illuminates the screen.
In 1978, a modified version without the light function, replaced by tritium tubes (caliber 1621), was developed under the name Project Alaska IV and offered to NASA for Shuttle missions. The latter tested them in training but also aboard the Shuttle, but in the end, the Moonwatch remained the best choice.
