Omegas earn common interest among LED watch collectors and they shurely
deserve it. Though there is some confusion regarding the model
names also because Omega itself used different names in their
documentations like Time Computer, Digital or Constellation. The
names in the list below reflect an average of the mainly used
ones for each model.
The modules caliber 1600 und 1601 were obtained from Pulsar (equal to 201 and 301), as well as the cases obviously were made by the manufacturer of the Pulsar cases. Because it seem the "parallel model" to the Omega Time Computer 1, the Pulsar P2, was not distributed in Europe the Omega TC1 should have been the very first LED watch on the european market in fall 1973. After this cooperation with Pulsar ended elektronics for the calibers 1602 and 1603 were obtained from Frontier.
This is a list of all Omega LEDs that were available:
|Swiss ref.||Caliber||Version||Historical prices|

|Time Computer 2||3960831||1601||yellowgoldplated||DM 2000,-|
|Time Computer 2||3960832||1601||stainless steel||DM 1500,-|
|Omega Digital 1||3960833
|Omega Digital 2||3960836

to set an Omega?
Caliber 1600, 1601: Place the magnet into the right slot of the case lid (view from upside) until the forthcomming minute is reached. At second 0 push the time demand button (right) to start the watch. After that place the magnet into the left slot to set the hour.
Caliber 1601: To set the day press both buttons and place the Magnet into the left slot. AM - point up, PM - point down. To set the month press the date button (left) and place the magnet into the left slot.
Caliber 1602, 1603: By pressing the set button (at three o'clock) the watch enters the setting mode and moves forward in it. By pressing the demand button you can change the settings.
Which batteries to use?
The most economic solution for those who can change batteries themselves is the alkaline button cell AG12. It has about 35% less capacity than the comparable silver oxide type 386, but it cost one fifth - only a few cents at a wholesaler. For safety reasons the usage of spacers (rubber o-ring for example) at the calibres 1600 and 1601 is recommended, regrettably the original very big button cells are no longer manufactured.
