Belisar Date Sport

Belisar Date Sport


The Belisar Date Sport is the very definition of straightforward, yet its simple, minimalist design leaves a striking impression. The distinctive stainless steel case with a diameter of 45 mm features the screwed-on flanks that are typical of the Belisar line, but coated in rubber on this version, for a decidedly sporty look. As with the watch glass itself, the rotating bezel is made from highly durable and scratch-resistant sapphire crystal, as are also the luminescent numbers and markers safely guarded beneath it. The crown and sapphire crystal case back are both screwed in place, to ensure that the watch is water-resistant up to a pressure of 20 bar. Thanks to the two interchangeable straps, one of stainless steel and one of NATO-textiles, the look of the watch can be effortlessly adapted to suit any style or occasion.

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.

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.
