Vintage Omega quartz watches
Omega's own vintage database lists 418 quartz references, the first in 1970. 139 were first made in the 1970s and 231 in the 1980s, across the De Ville, Seamaster and Constellation lines. The reference inside the caseback tells you which quartz calibre is in yours, and the calibre tells you which parts it takes.

Electroquartz, Megaquartz, Time Computer and Marine Chronometer
The early quartz Omegas carry names of their own. These are the names Omega's database gives, with the calibre it lists for each reference.
| Name | Reference | Year | Calibre | Case |
|---|---|---|---|---|
| Electroquartz | BA 396.0802, ST 196.0005 | 1970–1976 | 1300 | 18k gold or steel, 37 × 44 mm |
| Electroquartz | ST 196.0008, ST 396.0807 | 1972–1973 | 1301 | Stainless steel |
| Electroquartz | BA 191.0004 | 1974 | 1302 | 18k gold |
| Time Computer I, II, III | 396.0812, 396.0831/0832, ST 396.0833 | 1972–1975 | 1600, 1601, 1602 | Digital; gold, gold-filled or steel |
| Megaquartz | BA 396.0806 | 1973 | 1510 | 18k gold |
| Megaquartz | DD 396.0810, ST 196.0038 | 1973–1974 | 1310 | Steel, or steel with a gold bezel |
| Marine Chronometer | ST 398.0836 | 1974 | 1511 | Stainless steel |
| Marine Chronometer | ST 398.0832 | 1975 | 1516 | Steel with a solid gold bezel |
| Chrono-Quartz | ST 396.0839 | 1976 | 1611 | Stainless steel, Seamaster |
“Megaquartz” covers two different movements in Omega's records: the 1510 in the gold BA 396.0806, and the 1310, which the database also lists as “Megaquartz 32 kHz” on two 1974 references (Seamaster ST 196.0023 and Genève MD 196.0030). The Marine Chronometers are Constellations, on the 1511 and 1516. We don't hold Omega's parts lists for the 1300, 1510, 1511, 1516 or the Time Computer calibres yet, so they have no parts link here.

Electronic is not quartz. The Omega Electronic and f300 watches of the same years run on a tuning fork. Omega's database lists 45 tuning-fork references separately from the quartz ones.

The common quartz calibres, from the factory catalogue
Every quartz calibre we hold from Omega's GF 620-6 and GF 620-7 catalogues runs at 32,768 Hz.
| Calibre | References | Created | Size | Jewels | Notes |
|---|---|---|---|---|---|
| 1342 | 34 | 1977 | 25.60 mm, 4.20 tall | 7 | Date. Built on the 1340; the 1345 is the day-date version. |
| 1430 | 26 | 1983 | 23.30 mm, 2.15 tall | 6 | Date and end-of-life indicator (IFP). The 1431 is its chronometer version. |
| 1455 | 16 | 1985 | 13.00 × 15.15 mm | 6 | Small shaped. Borrows six parts from the 1375. |
| 1310 | 15 | 1974 | 29.00 mm, 6.35 tall | 8 | Day-date. The “Megaquartz 32 kHz” in Omega's database. |
| 1365 | 15 | — | — | — | Parts list not in our data yet. |
| 1330 | 14 | 1976 | 23.30 mm, 3.50 tall | 3 | No date. |
| 1377, 1378, 1380, 1387 | 13, 12, 13, 10 | — | — | — | Parts lists not in our data yet. |
| 1332 | 12 | 1980 | 25.60 × 28.00 mm, 2.90 tall | 17 | Shaped. The 1333 is its chronometer version; the 1337 adds a date and IFP. |
| 1450 | 9 | 1983 | 13.00 × 15.15 mm | 10 | Small shaped. Total height 2.10 or 2.46 mm, depending on the battery. |
| 1350 | 6 | 1977 | 13.00 × 15.15 mm | 2 | Small shaped, built around a framework with the motor; a short parts list. |
We also hold the 1320, 1325, 1340, 1345 and 1375. Among the Constellations, look for the chronometer versions: the 1333 differs from the 1332 in just two parts, the train wheel bridge and the module cover, with the same jewel count. Certification is the difference, not jewelling.
Renumbered in the 1990s. Omega renumbered the 1430 as the 1530 and the 1455 as the 1456 after a 1995 finish upgrade. Plates, bridges and circuits do not interchange between old and new; the basic components do.
Find the calibre number on yours
Start with the reference inside the caseback: the reference lookup gives the calibre Omega lists for it. To check the movement itself, the number is not always on the plate. Omega's catalogue says where it is:
| Calibre | Calibre number | Movement number |
|---|---|---|
| 1310 | Wheel train bridge 1310.9001 | Same bridge |
| 1320 | Electronic module 1320.9150 | Same module |
| 1325 | — | Electronic module 1325.9150 |
| 1330 | Plate 1330.9000 | Same plate |
| 1332 | Module cover 1332.9655 | Train wheel bridge 1332.9005 |
| 1333 | — | Module cover 1333.9655 |
| 1340 | Train wheel bridge 1340.9005 | Same bridge |
| 1342, 1345 | — | Train wheel bridge 1342.9005 or 1345.9005 |
| 1350 | Framework | Battery clamp 1350.9033 |
| 1375 | Train wheel bridge 1375.9005 | Same bridge |
| 1430 | Plate | Train wheel bridge 1430.9005 |
| 1450 | Electronic module 1450.9600 | Train wheel bridge 1450.9005 |
| 1455 | Train wheel bridge 1455.9005 | Same bridge |
A dash means the catalogue gives only the movement number's place for that calibre.
Parts and batteries
- Electronic parts are numbered in a 9xxx series (1325.9150, 1332.9655, 1430.9005). Search by the full number in the parts finder; it gives every calibre each part fits.
- Soldered parts on the 1332: four parts are soldered to the electronic module and cannot be replaced on their own.
- Borrowed parts: the 1455 takes six parts from the 1375; the 1345 takes two from the 1342; the 1340 takes one from the 1310 and one from the 1320.
- Batteries: Omega's technical guide for the 1430 gives a 9.50 × 1.60 mm battery, type 373. The 1450's catalogue lists two batteries, 9938 and 9939, which is why its total height is 2.10 or 2.46 mm.

What it's worth
A vintage quartz Omega is worth what the same reference with its correct calibre has actually sold for: use the “sold” links on this page, not asking prices. The checks are the same as for any Omega: the reference, the calibre Omega lists for it, and an original dial. What's my Omega worth? explains the method. The letters in front of the reference give the metal; Gold or plated? shows how to tell solid gold from plate.
Which quartz calibre is in yours?
The reference, the calibre and the dial have to agree. Six photos and the weight, and I check them against Omega's own records and put it in writing. Nothing to pay until I confirm the photos can answer it.
The Bench is a free game in your browser or on your phone: take a real vintage Omega calibre apart and build it back up, part by Omega part number.
Questions people ask
Did Omega make quartz watches in the 1970s?
Yes. Omega's vintage database lists 418 quartz references, the first in 1970: the Constellation Electroquartz on the calibre 1300. 139 were first made in the 1970s and 231 in the 1980s.
What is an Omega Megaquartz?
Megaquartz is a name Omega used on early quartz watches. Its database lists the gold Constellation Megaquartz BA 396.0806 (1973) on the calibre 1510, and Megaquartz references on the calibre 1310, which it also lists as "Megaquartz 32 kHz".
How old is my Omega Megaquartz 32 kHz?
Omega's database lists the calibre 1310 in 15 references from 1973 to 1980. The steel Genève references on it are ST 196.0038 (1974) and ST 196.0065 and ST 196.0066 (1976). The movement serial gives a second date, but the two published serial tables disagree in the 35-million range: about 1972 in one, 1976 to 1977 in the other. No 1310 reference appears before 1973, so the reference inside the caseback is the better guide.
Is the Omega Marine Chronometer quartz?
Yes. Omega's database lists two Constellation Marine Chronometers: ST 398.0836 (1974) on the calibre 1511 and ST 398.0832 (1975) on the 1516, both quartz.
What movement is in my vintage Omega quartz watch?
The reference inside the caseback tells you: Omega's database lists the calibre for each one. The most listed are the 1342 (34 references), 1430 (26), 1455 (16) and 1310 (15). The reference lookup gives the calibre for yours.
Where is the calibre number on an Omega quartz movement?
It depends on the calibre. Omega's catalogue puts it on the plate of the 1330 and 1430, on the train wheel bridge of the 1340, 1375 and 1455, and on the electronic module or its cover on the 1320, 1332 and 1450.
Is an Omega Electronic or f300 a quartz watch?
No. The Electronic and f300 watches run on a tuning fork. Omega's database lists 45 tuning-fork references separately from its quartz references.
Are vintage Omega quartz watches worth anything?
A vintage quartz Omega is worth what the same reference with its correct calibre has sold for. Check sold prices, not asking prices, and check that the reference, the calibre and the dial agree.
