The only grade of steel used by Union Glashütte is stainless steel 316L. This alloy is characterised by its excellent anti-corrosion properties. For the relevant watches, the following components are produced from this material: cases, bracelets, double fold fasteners with two push buttons (decorated).

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.

All Union Glashütte watches are water-resistant as follows: Men's watches up to 10 bar (100 m) Ladies' watches up to 5 bar (50 m) Gold watches up to 3 bar (30 m). The water resistance cannot be guaranteed indefinitely. It may become compromised by ageing of the seals or knocks to the crown or push-buttons. We therefore recommend that you have the water resistance of your watch checked once a year by an approved Union Glashütte Service Centre and, if required, that you replace any defective parts. Do not open the watch yourself under any circumstances.
