Omega Caliber 1670: Quartz Hybrid Engineering with a Clean Aesthetic

The Omega Caliber 1670 is a quartz multifunction analog-digital movement developed in the early 2000s as a continuation of Omega’s long-standing tradition of hybrid technology. It was designed for users who required daily functionality beyond timekeeping, while still maintaining the refined look of an analog watch.

Used in niche models—particularly within the Seamaster family and in some special-edition hybrid watches—the 1670 provided core digital features like dual time zones, alarms, and chronograph, seamlessly integrated into an analog display without sacrificing legibility or elegance.

Technical Specifications

• Type: Quartz analog-digital hybrid

• Functions:

  • Analog time display (hours, minutes, seconds)

  • LCD digital screen (typically at 6 o’clock or embedded within the dial)

  • Digital time (12/24h)

  • Second time zone (T2)

  • Alarm

  • Chronograph (stopwatch)

  • Countdown timer

  • Calendar (day/date)

• Battery: CR1620 lithium cell

• Battery Life: Approx. 2 years

• Accuracy: ±15 seconds/month

• User Controls: Two or more pushers and/or crown

• Backlight: No

• Sound Alert: Yes (digital alarm chime)

The Caliber 1670 is likely a derivative of ETA’s multifunction quartz platform, but modified and programmed to meet Omega’s quality standards and integrated into sport-luxury designs.

Watches Featuring Caliber 1670

Omega used the Cal. 1670 in a limited number of quartz hybrid models, mostly in the Seamaster line and in a few market-specific special editions. These watches often featured:

• Stainless steel or titanium cases

• Diver-style bezels (on Seamaster variants)

• Analog-dominant dials with discreet LCD windows

• Integrated or tapered bracelets

• Strong water resistance (typically 100–300m)

They were created for users who wanted the reliability and versatility of a digital sports watch, but with the upscale appearance of an Omega analog timepiece.

Use and Functionality

The Caliber 1670 made it easy to switch between functions with just a few button presses. Key highlights include:

• Dual time zones: great for travelers

• Audible alarm: useful for daily reminders

• Chronograph and countdown timer: for casual sport timing

• Date and day readout: practical for business or scheduling

Unlike some earlier multifunction movements, the 1670 placed emphasis on clarity and ease of use, often with a less intrusive LCD interface that preserved the classic appearance of the dial.

Service and Maintenance

The 1670 is relatively low-maintenance:

• Battery replacement every 2 years

• Occasional gasket servicing for water resistance

• Digital module generally stable, though fading LCDs may occur over time

While Omega no longer produces the 1670, parts can sometimes be sourced from donor watches, and Omega’s service network can provide support for functioning units.

Collector Value

Due to its limited use, watches powered by Caliber 1670 are not common. They appeal to collectors and enthusiasts who appreciate:

• Hybrid Omega designs

• Functional elegance

• Quartz precision with analog charm

• Durability in everyday wear

These models offer excellent value as under-the-radar Omegas, combining brand prestige with practical digital tools.

Final Thoughts

The Omega Caliber 1670 is a quietly capable movement that reflects Omega’s thoughtful approach to multifunction quartz innovation. For those who want a reliable, versatile timepiece with both digital features and analog sophistication, the 1670 remains a smart and rare find in the world of hybrid luxury watches.
