Swiss Military Solar-Sportuhr – Komplett schwarz, Kautschuk | SMS34102.03

The SMS34102 is for you if you want one dependable analogue watch for the office, travel, weekends and outdoor activities. You can wear it regularly without planning around routine disposable battery changes, while natural and artificial light help maintain its energy reserve.

Choose this model if you prefer a visible sports-watch design over a discreet dress watch and want a watch that combines Swiss Made quality with practical features for daily use. The stainless-steel bracelet works well for everyday wear, while compatible rubber bands let you adapt the watch for sport or a lighter feel.

To maintain optimal performance, regularly expose the watch to light sources. Direct sunlight is most effective, with just 2 minutes providing enough power for a full day. Under a fluorescent lamp, 35 minutes will fully charge the battery, while 4.4 hours of indoor lighting achieves the same.

After a full charge, the SMS34102.01 runs for up to eight months without additional light. This reserve supports operation when the watch is stored, covered by clothing or exposed to limited light.

The eight-month figure describes the maximum operating reserve after a full charge. It does not represent unlimited operation in darkness. When the energy reserve is depleted, the watch must be exposed to light before normal operation can resume.

After complete discharge, expose the dial to light until the movement restarts. Continue charging before wearing the watch so that the energy reserve is sufficient for normal operation.

The solar movement includes protection functions for the rechargeable energy cell:

• Quick-start function: The movement can resume after initial exposure to light.
• Battery protection mode: The movement reduces energy consumption when the charge level becomes critically low.
• Overcharge protection: The charging system protects the energy cell against excessive charging.

For longer storage, pull the crown to its outermost position to stop the movement and reduce energy consumption. Return the crown to its normal position before wearing the watch again. Follow the operating instructions for the correct procedure.

A solar cell beneath the dial converts natural and artificial light into electrical energy. The movement stores this energy in a rechargeable energy cell and uses it to operate the watch.

The watch recharges while it is exposed to light. Regular wear helps maintain the energy reserve without a daily charging routine or regular disposable battery changes.

Charging speed depends on the light source, its intensity, the distance from the watch, the angle of exposure and the remaining charge.

The Easy-Click system allows compatible bands to be changed without tools. Adapt the watch to everyday wear, travel, sport or your personal style. Find compatible rubber bands here.

The black dial features luminous green hands and hour markers. The red second hand creates visual contrast and adds a sporty accent.

The luminous material must be exposed to light before it glows in darkness. Brightness and duration depend on the intensity and duration of the previous light exposure.
