The Omega Caliber 1428 is a quartz analog movement developed in the early 1980s, during Omega’s golden era of quartz experimentation. Like its sibling calibers (such as the 1420, 1422, and 1430), the 1428 was tailored for thin, stylish watches in the De Ville, Constellation, and Seamaster lines. Its compact footprint and two-hand layout made it ideal for uncluttered dials and elegant designs.
With an emphasis on accuracy, slimness, and ease of use, Caliber 1428 exemplifies the Swiss response to growing consumer demand for reliable and fashionable quartz timepieces.

Minimalist dials with stick hands and applied markers
A date window at 3 o’clock
These models reflected 1980s fashion values—favoring slimness, refinement, and quiet functionality over showy features.
As with other Omega quartz movements of the period, the 1428 was:
Highly accurate, with only minor monthly deviation
Battery efficient, especially without a seconds hand
Ideal for everyday wear, travel, or professional use
Silent in operation, making it discreet and elegant
The movement’s layout and low energy draw ensured excellent longevity, even in compact watch cases with minimal internal space.
Although the Caliber 1428 is no longer in production, it remains fully serviceable:
Battery changes every 2 years
Gasket and seal replacements if water resistance is needed
Donor movements and replacement parts are still found via vintage watch specialists
Given its simplicity, many qualified watchmakers can maintain this movement with ease.
The Omega 1428 holds value for collectors who appreciate:
Vintage Swiss quartz engineering
Slim, stylish Omega watches from the 1980s
Reliable, affordable dress models
Restoration of ladies’ or compact unisex pieces
It’s a practical entry into the world of vintage Omega, especially for those who prioritize ease of use and elegant aesthetics.
The Omega Caliber 1428 is a fine example of Omega’s quartz innovation during a key transitional era in horology. Built for quiet excellence, it remains a hidden gem in vintage collecting—combining Swiss precision, timeless styling, and everyday reliability.
