5 Months Power Reserve

SMS34113 Solar Chronographs

The Swiss Military SMS34113 is an analogue solar watch with chronograph function for people who want to wear a reliable watch and reduce the need for regular battery changes. Its energy cell recharges in natural or artificial light. When fully charged, the SMS34113 offers up to five months power reserve.

The SMS34113 Solar Power Watch combines classic timekeeping with practical time measurement. You can start, stop and reset time intervals while normal timekeeping continues to run independently. Sapphire crystal, luminous hands and 100 m water resistance make it your companion for everyday wear, business casual, travel and active leisure.

Why a Solar Chronograph Watch?

The SMS34113 is worth considering if you want your watch to be readily available in everyday life without having to worry about regular battery changes or daily charging. It combines:

  • analogue timekeeping for quick, familiar readability,
  • chronograph function for starting, stopping and resetting time intervals,
  • solar power supply that recharges the energy cell in light,
  • up to five months power reserve when fully charged,
  • sporty everyday practicality for work, travel and active leisure.

The SMS34113 is not a smartwatch and doesn't try to be: the solar technology works in the background while you wear an independent analogue watch with clear functionality and distinctive Swiss design.

What Is a Solar Chronograph and How Does the SMS34113 Work?


A chronograph is an analogue watch with an integrated stopwatch function. With the SMS34113 Solar Chronograph wristwatch, you can start, stop and reset time intervals while normal timekeeping continues to run independently.

All six SMS34113 designs have the same functions and operation. Differences in colour, coating or strap don't change this. A brief overview of operation can be found in the instruction manual for Swiss Military solar watches.

The SMS34113's energy cell is charged by light. Solar technology powers the analogue quartz movement and chronograph functions. Solar power therefore eliminates the need for regular battery replacement during normal use.

How Long Does the SMS34113 Run and How Is It Charged?

When fully charged, the SMS34113 offers up to 5 months power reserve. This figure does not mean the watch runs indefinitely without light.

The SMS34113 charges its energy cell through natural or artificial light. Direct sunlight is not required. Daylight and artificial light also charge the watch; however, depending on light intensity and distance, the process may take longer.

The following charging guidelines apply to the SMS34113: Approximately 2 minutes of direct sunlight or about 35 minutes under a fluorescent lamp provide energy for roughly one day of running time. A full charge under indoor light takes approximately 4.5 hours.

Actual charging time depends on factors including light intensity, distance, exposure duration and charge level. After prolonged storage in darkness, a charging period may be required before next use.

SMS34113 or SMS34102: Which Solar Collection Is Right for You?

Both collections use solar power. The right choice depends on whether you're looking for additional stopwatch functions or prefer a streamlined analogue display with the longest possible power reserve.

The SMS34113 is right for you if you want to time intervals and prefer a sporty, functional chronograph dial. Solar power eliminates the need for regular battery replacement during normal use.

The SMS34102 is the better collection if a cleaner, more streamlined display and the longest possible power reserve are more important to you than additional chronograph functions. The solar sports watches offer 8 months power reserve. More information can be found in the SMS34102 solar sports watch collection.
