Omega Caliber 1637: Quartz Chronograph Precision in the Seamaster Polaris

The Omega Caliber 1637 is a quartz chronograph movement developed by Omega in the late 1990s, known primarily for its use in the Seamaster Polaris Chronograph line. This caliber represents Omega’s push to deliver mechanically reliable and functionally rich quartz timepieces in its sports watch family, offering precision timing capabilities and classic styling in a more accessible format than full mechanical chronographs.

Unlike the hybrid analog-digital multifunction calibers in the 1600-series, the 1637 is a pure analog quartz movement—with a traditional chronograph layout, three subdials, and central hands—all controlled through standard pushers.

Watches Powered by Caliber 1637

This movement was primarily used in the:

• Omega Seamaster Polaris Chronograph

• Various special editions and market-specific Polaris quartz chronographs

These watches typically featured:

• Titanium or bi-metal (titanium and gold) cases

• Integrated bracelet systems

• Satin or brushed case finishes

• Distinctive “bullseye” dial layouts with three subdials

• Fixed bezels (non-diving style)

While Polaris models had roots in Omega’s 1980s multifunction era, the later chronograph variants with the 1637 leaned more toward sport-luxury styling, targeting active wearers who appreciated legibility and accuracy without the maintenance of a mechanical chronograph.

Reliability and Servicing

The Omega 1637 is known for being highly reliable. As a quartz chronograph, it offers:

• Instant start/stop/reset function

• High precision with 1/10-second measurement

• Minimal service needs, mostly limited to battery replacement

Omega-certified technicians and experienced watchmakers can easily maintain this caliber, and parts from the ETA base movement remain available.

Collector Appeal

While not widely known, the Caliber 1637 holds growing interest among collectors who appreciate:

• Late-era Polaris watches

• Retro-sporty design language

• Quartz chronograph functionality without the bulk

• Omega craftsmanship at affordable prices

Many of these watches were produced in limited regional runs, making well-preserved examples harder to find. Clean dials, functioning chronograph hands, and original bracelets enhance their value.

Final Thoughts

The Omega Caliber 1637 bridges the gap between high-precision quartz reliability and classic chronograph design. With roots in the versatile Polaris line, it offers users a stylish, maintenance-friendly watch with real utility. For those seeking an Omega chronograph without the cost or complexity of mechanical options, the 1637 is a practical and collectible choice.
