Omega Caliber 1675: Refined Hybrid Functionality in Omega’s Quartz Legacy

The Omega Caliber 1675 is a quartz analog-digital multifunction movement, part of Omega’s 16xx series, and among the most refined in terms of functionality, interface design, and reliability. Introduced in the early-to-mid 2000s, the 1675 movement was used in select Omega Seamaster and Constellation hybrid models, offering a discreet digital window within a traditionally styled analog watch.

As such, the Caliber 1675 represents a blend of practicality and prestige, perfect for professionals who needed more than just timekeeping on the wrist.
