Saphir
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.

Gold
Refined gold is very soft and is the most ductile of all metals. Soft, refined gold is a material that is ill-suited for use in jewellery, watches, coins, etc., and is therefore alloyed with other metals to alter its hardness, strength and colour, as well as to improve polishing results and bring down the price.
For its cases, crowns and buckles, Union Glashütte only uses gold alloys with a copper content and with 750 parts per thousand of pure gold (18 carat). This produces a rose gold tone.
