Omegamatic caliber
Omegamatic used Omega caliber 1400 (ETA 205.111 Rhodium plated), 17 jewel autoquartz (not thermocompensated) action with around 100 hours power reserve. This caliber has the option of handbook winding to get the initial power to the capacitor. The mechanism alerts cheap power keep by migrating the seconds hand in 4 seconds intervals. The Omega 1400 caliber has a slow date alteration, which commonly takes around 1.5 hours to change over.
Production of ETA 205.111 began in 1996. It was superseded by ETA 205.911, which replaced the capacitor with a rechargeable battery.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 secondhand 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 drip, 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 other failures, the best option would be getting a watch with a 205.911 caliber (Tissot PR100 autoquartz) and use it because spares. The use of a Swatch autoquartz it namely not suggested for these carry the minor ETA 205.711 15 gem caliber.
ETA 205.111 technical communication document, in electrical test partition,
Take Good Care Of Your Platinum Jewelry, states that capacitor voltages will fluctuate from 0 to 2.4V. It also documents that external power afford tests are to be run with 1.55V (measured with the capacitor in area).In ETA 205.911 technical communication document, Interchangeability (List of stuff) section, it is listed that the major parts that disagree from 205.111 caliber are Generator (chapter not. 20.590.00 for 205.911 and part no. 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 catalogue the generator for caliber 205.911 (Article no, 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 though MT920 is devised to last 500 charge-discharge cycles, due to lack of lawful documentation, it is not remove how long this titanium lithium rechargeable battery will last when used in Omega 1400 caliber.
Operation of Omegamatic mechanisms
An oscillating heaviness (selfwinding machinery in a orthodox watch) transmits the mechanical energy to the micro generator via the microbarrel. The generator converts this mechanical energy into electrical energy and stores it in an accumulator (Capacitor for caliber 1400).
The accumulator supplies the integrated circumference with energy. Regulated by the quartz, the integrated circle generates the control whistles of the stepper motor which transmits these thrusts to the gear exercise whose wheels and the joined hands are displaying hours, minutes, seconds and the date.
Caliber 1400 can charge the capacitor by rotating the crown of the watch. It will require over 40 revolutions before the low power arrow stops.
