Union Glashütte uses only 316L stainless steel for its cases, bracelets, and clasps. This alloy is characterized by high corrosion resistance, skin compatibility, and durability, providing a reliable foundation for everyday use. At the same time, finely machined and polished surfaces contribute to the watch's distinctive appearance.

While stainless steel remains durable in use, it can—especially polished surfaces—acquire minor marks. To preserve the surface for as long as possible, it is recommended to avoid contact with hard or abrasive materials and to store the watch separately from other objects. After exposure to salt water or chlorine, it should be rinsed with clean water and dried with a soft cloth.

Regular cleaning with a microfiber cloth is sufficient for maintenance; a slightly damp cloth can be used if necessary. Avoid aggressive cleaning agents or abrasive materials. The finest signs of wear can be reduced through professional servicing, thus preserving the original finish for years to come.

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 primarily uses calfskin leather – smooth or crocodile-embossed – as well as cowhide, horsehide, and goatskin for its watch straps. As natural materials, they give each watch an individual character and develop a distinctive patina over time.

Protect from water, high humidity, and intense sunlight.

Do not wear while showering, swimming, or playing sports.

Avoid contact with strongly colored materials (e.g., denim).

Dry gently after exposure to moisture – without heat.

Slight variations in color and surface are typical of the material and emphasize its individual character. Depending on use, the material will change over time – therefore, replacing the strap is a natural part of long-term use.

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.
