Belisar Chronograph Moon Phase

Belisar Chronograph Moon Phase

D907.425.46.017.01

The moon phase display is one of the most traditional complications in watchmaking. UNION GLASHÜTTE has given it a modern facelift. Sleek, sporty, enduring - this is how the sophisticated Belisar Chronograph Moon Phase presents itself from now on. A round stainless steel case with a diameter of 42 mm and a striking yet classic dial design worthily sets the scene for the chronograph. The pushers of the chronograph mechanism are joined by a discreet corrector at 10 o'clock, which allows the day of the week to be set separately. Anti-reflective sapphire crystal on both sides and water resistance up to 10 bar (100 m) complete the list of its attributes. On the inside beats the automatic caliber UNG-25.S1 with silicon balance spring and an improved power reserve of at least 65 hours. The dial comes in a classic white color with blue elements and is divided as follows: The upper half of the dial displays the date. The chronograph functions are rounded off by a 60-second counter and a 12-hour counter at 6 o'clock, as well as a 30-minute counter at 12 o'clock. The dial also includes two windows indicating the weekday and the month. The counter at 9 o'clock has one hand for the 24-hour display and another hand for the seconds display. The moon phase display adds a stylish flourish with a gold-coloured moon set against a blue sky. The design is completed by a brown calfskin strap with crocodile embossing.

silicon balance spring

silicon balance spring

UNION GLASHÜTTE uses Silicon, a chemical element of the family of metalloids, in the manufacture of balance springs. By use of Silicon, our watches are insensitive to magnetic fields, temperature fluctuations and shocks. They are very stable in shape and resistant to oxidation. The silicon spiral guarantees higher power stability in our mechanical movements - so your watch runs precisely anytime, anywhere. You can recognize the use of the silicon spiral in your UNION GLASHÜTTE watch by the Si-poster that our watchmakers set and align by hand.
STAINLESS STEEL

STAINLESS STEEL

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.

Saphir

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.
Leather straps

Leather straps

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.
    Gold

    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.
    Water resistance

    Water resistance

    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.
