Sirona Date

Sirona Date


The precision of a Glashütte watch – the sophistication of jewellery: The Sirona features a dainty stainless steel case measuring only 32 mm in diameter. Its elongated lugs, the beautifully shaped crown and the dark red leather strap give the watch its unmistakeable look. In addition to this, a double-sided anti-reflective sapphire crystal provides the clearest possible view of the dial's eight sparkling diamonds and its sunburst finish. This red ladies' watch is guaranteed to turn heads.

The Sirona blurs the line between timepieces and jewellery. Exuding charm and elegance, these delicate ladies' timepieces hug the wearer's wrist, discretely emphasising their personal style. Dials in glossy enamel or shimmering mother-of-pearl provide the perfect backdrop for a sparkling adornment of diamonds. Luxurious details in 18-carat gold also provide elegant accents.

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.
