Overall Impression
The watch introduced here is the IWC Ref. 910.
One of the defining features of this model is its gold-tone design.
The brand signature, dial, hands, and indexes are all finished in gold. However, its 34mm case size and the proportions of its design prevent it from feeling overly flashy.
At first glance, it appears to be a bold gold watch, but once on the wrist, it has a calm and understated character.
The appearance of the watch changes depending on the light, offering a slightly different impression each time you check the time.
It has a different kind of appeal from a simple white dial, and even after wearing it throughout the day, you may find yourself glancing at your wrist.

The watch features a stainless steel screw-back case.
For a vintage watch, it was designed with practicality in mind. However, as with any vintage watch, care should still be taken regarding water resistance.
Despite its distinctive appearance, it feels light on the wrist. It has a noticeable presence without feeling excessive, giving the watch a cohesive overall design.
Movement
Cal. 89 – One of IWC’s Best-Known Movements
The Ref. 910 is powered by the Cal. 89.
Designed by Albert Pellaton in 1946, the Cal. 89 is one of the defining hand-wound movements of the post-war era.
It is regarded as one of IWC’s best-known movements and remained in production for approximately 30 years, with around 226,000 examples produced during that time.
Its balanced dimensions, durable construction, and ease of servicing are among the reasons it continues to be highly regarded today.
Although normally hidden beneath the case back, the movement is beautifully finished, reflecting the careful craftsmanship that characterized IWC during this period.
Conclusion
The combination of the Ref. 910 and the Cal. 89 reflects IWC’s long history of building watches designed to last.
Despite its strong gold-tone appearance, the overall design remains restrained.
It is a vintage IWC that combines elegance with restraint, making it easy to enjoy in a variety of settings even today.
