PRODUCT INFORMATION & OPERATING INSTRUCTIONS
ENERGY SUPPLY SYSTEM
Your SOLARUM's energy supply system uses sunlight to generate and store energy – for self-sufficient and sustainable operation. Here you will find all the important information about it:
ENERGY SUPPLY
The SOLARUM is a high-quality solar watch that harnesses energy from sunlight and artificial light alike. A solar cell beneath the dial converts light into electrical energy to charge the integrated battery. This battery reliably powers the watch movement, even in the absence of light. Regular exposure to light, preferably natural daylight, guarantees consistently accurate operation.
CHARGING TIME
Charging Times for Your SOLARUM Watch ☀️ Sun (clear sky) 2 min → 1 day of operation 7 hours → full charge 🌥️ Cloudy sky 11 min → 1 day of operation 1.5 days → full charge 💡 Fluorescent lamp (30 W, 20 cm distance) 35 min → 1 day of operation 5.2 days → full charge 🏠 Indoor lighting 4.4 hours → 1 day of operation 40 days → full charge
ENERGY AND STORAGE CAPACITY
- Power reserve in complete darkness: up to 8 months - High-performance battery: virtually unlimited lifespan at full capacity - Total service life: 12–20 years - No battery replacement required
WARNING
⚠️ Avoid high temperatures above 60 °C (e.g., under incandescent or halogen lamps, or behind glass) to prevent damage. ⚠️ Do not use other rechargeable or silver oxide batteries — doing so may damage the watch movement and pose a risk to the wearer. Optional, more concise. ⚠️ Avoid temperatures above 60 °C (e.g., under incandescent/halogen lamps or behind glass) to prevent damage. ⚠️ Use only the supplied battery — other rechargeable or silver oxide batteries may damage the movement and endanger the wearer.
MATERIAL SPECIFICATIONS
In this section you will learn more about the materials used, the case design and special features such as coatings and water resistance of our SOLARUM.
WATER-RESISTANT
The SOLARUM watch is water-resistant up to 5 ATM, providing protection against splashes, rain, and short periods of immersion—perfect for everyday activities, handwashing, or showering. It is not suitable for swimming or diving.
CASE MATERIAL
The SOLARUM watch case is crafted from high-quality 316L stainless steel, a highly corrosion-resistant and robust material perfect for daily wear. It comes with a PVD coating in black, rose gold, or yellow gold, giving the case a long-lasting and elegant finish.
WATCH GLASS
Our SOLARUM watches feature high-quality sapphire crystal, distinguished by its exceptional hardness, scratch resistance, and optical clarity. It offers reliable protection for everyday wear and, thanks to its high transparency, allows for a clear view of the dial at all times – for a sophisticated, high-quality look.
BRACELET MATERIAL
Recycled Apple Bracelet: Crafted from leftover apple-processing materials, this vegan and environmentally friendly alternative to leather combines durability, style, and sustainability.

In this section you will find important information on the maintenance of your SOLARUM as well as on the warranty conditions – so that your watch works reliably and you know exactly what to do in the event of a service issue.
CARE INSTRUCTIONS
- Clean with a soft cloth regularly. - Keep the watch exposed to sufficient light, ideally sunlight. - Avoid storing it permanently in the dark. - Protect from extreme moisture, heat, and magnetic fields. - Check seals and charging function when necessary.
MAINTENANCE
Although solar-powered watches require minimal maintenance, we recommend professional servicing if accuracy decreases, charging becomes inconsistent, or water resistance is affected. In these cases, a specialist retailer should inspect the watch, and the seals, battery, or movement may need attention.
