Omegamatic caliber
Omegamatic used Omega caliber 1400 (ETA 205.111 Rhodium plated), 17 jewel autoquartz (not thermocompensated) campaign with around 100 hours power keep. This caliber has the option of handbook winding to get the initial power to the capacitor. The mechanism alerts low power reserve by migrating the seconds hand in four seconds intervals. The Omega 1400 caliber has a slow date alteration, which commonly takes nearly 1.5 hours to change over.
Production of ETA 205.111 started in 1996. It was displaced by ETA 205.911, which replaced the capacitor with a rechargeable battery. Technical documents of 205.111 caliber could be recovered from ETA customer service portal
The capacitor used in Omegamatic watches is a Renata GC920 (9.5 x 1.9 mm 2.4V 0.33F). in the event of failure due to electrolyte leak, this capacitor could be replaced by a Panasonic MT920 1.5V (ETA MT920/Citizen 298-177) rechargeable battery. Another compatible rechargeable battery is the Maxell TC920S lithium-ion cell (Seiko 3023 xxZ).
For additional failures, the best discretion would be obtaining a watch with a 205.911 caliber (Tissot PR100 autoquartz) and use it for leftovers. The use of a Swatch autoquartz it is not suggested as these carry the minor ETA 205.711 15 jewel caliber.
ETA 205.111 technical communication file, in electrical test partition, states that capacitor voltages will fluctuate from 0 to 2.4V. It also documents that external power afford tests are to be scamper with 1.55V (measured with the capacitor in location).In ETA 205.911 technical communication document, Interchangeability (List of substance) section, it is listed that the major parts that disagree from 205.111 caliber are Generator (portion not. 20.590.00 for 205.911 and portion not. 20.515.00 for 205.111) and accumulator (part no. 20.575.00 for 205.911 and part no. 20.802.00 for 205.111 - capacitor). Demo-version of the ETA ONLINE SHOP menu the generator for caliber 205.911 (Article no,Jewelry Display is the Key to Selling Jewelry , 04203.205111 (CS) / 251987) as part no. 20.515.00 (the same part digit for caliber 205.111) and it specifically mentions that it is compatible with calibers 1400 B, 205.911 C and 205.911 E.
Omega caliber 1400 is compatible with Panasonic MT920 (titular voltage of 1.5V). Even although MT920 is designed apt last 500 charge-discharge cycles, deserving to lack of official documentation, it is no remove how long this titanium lithium rechargeable power cell ambition last when secondhand in Omega 1400 caliber.
Operation of Omegamatic mechanisms
An oscillating heaviness (selfwinding machinery in a traditional watch) transmits the mechanical stamina to the mini generator via the microbarrel. The generator converts this mechanical stamina into electrical energy and stores it in one accumulator (Capacitor for caliber 1400).
The accumulator supplies the integrated circuit with energy. Regulated by the quartz, the integrated circle generates the control signals of the stepper motor which transmits these urges to the gear train whose cycles and the interlocked hands are displaying hours, minutes, seconds and the date.
Caliber 1400 tin dictate the capacitor by rotating the crown of the watch. It will require over 40 revolutions before the low power indicator stops.
