Belisar Chronograph

Belisar Chronograph


This sporty Belisar Chronograph measures a total of 44mm, comes with an unusual dial and new inner workings to the highest technical specifications. Ticking away inside is the first movement of its generation: The UNG-27.S1, which features a silicon balance spring and a high power reserve of 65 hours. The dark green and black dial with a colour gradient running from the inside out is guaranteed to turn heads. Large numbers in a blocky retro style reminiscent of the classic modern era, a pulsometer and typical retro elements such as the pump push-buttons, the slightly domed sapphire crystal and the railway track chapter rings round off the watch's typical vintage character. The timepiece also features a green nubuck leather cut edge strap with white bar tack stitch.

The Union Glashütte user's manual give information about the use, the settings and the maintenance of the different Union Glashütte watches.



The sapphire used by Union Glashütte for its crystals is a white, synthetic sapphire. Thanks to its hardness rating of 9, this crystal can only be scratched by very hard diamond-like substances. Union Glashütte watches only use double-sided anti-reflective sapphire crystals. As there are no reflections on the crystal, the full splendour of the dial is revealed.

silicon balance spring

silicon balance spring

UNION GLASHÜTTE uses Silicon, a chemical element of the family of metalloids, in the manufacture of balance springs. By use of Silicon, our watches are insensitive to magnetic fields, temperature fluctuations and shocks. They are very stable in shape and resistant to oxidation. The silicon spiral guarantees higher power stability in our mechanical movements - so your watch runs precisely anytime, anywhere. You can recognize the use of the silicon spiral in your UNION GLASHÜTTE watch by the Si-poster that our watchmakers set and align by hand.
