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.

Union Glashütte uses primarily calfskin for its straps, either smooth or with a crocodile skin finish, as well as cowhide, cordovan or goatskin.

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.
