About this watch

This is the second variation of this landmark watch we have had for sale (they only made three types). These watches have got to be one of the rarest production Speedmasters we have listed on our site and one of the most unique Omegas ever made. They were made exclusively in 1977 and sold throughout 1977 and 1978 only.

Original 1620 Movement

The watch movement is correct and original 1620 which is serviced and fully overhauled, even the light works! The case has not been touched as it was obviously as NOS and as such basically unworn). It even has the factory purple zappon coating on the case back. There are a few light marks on the case back and a small surface scratch on the crystal from storage and possibly someone trying to open the back at some point but nothing that detracts.

The watches movement is calibre 1620, not to be confused in any way shape or form with modern or even other vintage LCD movements. This movement has a circa 5 seconds per month accuracy as a result of a high quality 32Khz quartz resonator. The functions on the watch (which all work as they should) include:

  • Time/hour/minutes/seconds and day of week
  • 1/100 second chronograph able to accumulate to 0.1 seconds off 24 hrs
  • Split second chronograph
  • Lap time
  • Split/Stop of 2 consecutive times
  • Separately power light (working as it should)
  • Calendar programmed for leap year

This really is a special watch, there where very few of this type of Omega Speedmaster made and even fewer have survived unworn and functioning correctly, especially in basically completely unworn condition.  The watch is presented on a very rare grey period rally band with buckle.

One of the rarest digital pieces

This is a must for any budding Speedmaster collector, it has all the functions of a modern digital chronograph but knowing that it is without doubt one of the finest, rarest and most important LCD watches ever made. This has to be the epitome of 1970’s technology and style and it is true testament to these remarkable watches that they are still working as good today as they did when they where new. Do not confuse this watch with your run of the mil digital watch, this is the Bugatti of the LCD watch world.
