Care for your Suunto watch and straps




We recommend treating your Suunto watch just like any other part of your wardrobe. Get a spare strap or two for your watch, change them depending on what you are wearing or doing, and wash the watch body and the straps regularly.

On this page, we’ve gathered instructions for cleaning and caring for your watch by strap material, since different materials require a little different care.

Watch body

We recommend you wash the watch body after every workout to remove sweat, dander, and residue of any body lotion or cream you might have on your skin. If the watch has a silicone or elastomer strap, the same cleaning instructions apply also to the straps.

Care instructions:

Use lukewarm water and mild hand soap to wash the watch body, rinse well with water and pat the device dry with a towel. Use a dampened cloth to remove any stubborn dirt or stains, and a soft-bristled toothbrush to clean debris away from charging contact points or cavities on the device.

Silicone or elastomer straps

Many Suunto watches come with a strap made of hypoallergenic silicone. Silicone feels soft and comfortable against the skin and the material is easy to clean, making silicone straps ideal for swimming and sports where you sweat a lot. Mostly used in our older watches, elastomer straps are a bit stiffer than silicone ones, but also suitable for high output activities.

Care instructions:

  • Regularly take the watch off your wrist, wash the watch and the strap with mild hand soap and water, rinse thoroughly and dry it well with a towel before putting it back on.
  • We recommend washing the watch body and the strap after every heavy workout
  • To remove build-up of lotions and oils (such as sunscreen, insect repellent and moisturizers) that can be trapped beneath the strap: use mild hand soap, rinse thoroughly and dry well with a towel.
  • For tough spots, stains or buildup, scrub with a wet, soft-bristled toothbrush.



Leather straps

The performance and lifespan of leather straps can differ from one strap to the next given the natural variation in the material. Usage has a significant impact on the performance and lifespan of leather straps, and contact with fresh water, salt water, and perspiration may change the color and odor of the strap.

Leather straps are designed for casual daily wear, but wearing them day and night will impact their qualities and lifespan, so we recommend taking the watch off for the night.

If you want to wear the watch overnight e.g. for sleep tracking, we recommend changing the strap to one of our more breathable silicone designs. Also, if you intend to swim, snorkel or participate in high-output activities with your Suunto watch, we recommend using a silicone strap.

Environmental sustainability

Suunto leather straps are made of high-quality Italian vegetable-tanned leather. Vegetable-tanned leather doesn’t contain any toxic substances such as azo-dyes, nickel, PCP or chrome VI and its production cycle has a low impact on the environment. The rawhides used for our leather straps are by-products of the food industry, so no animal is killed for its skin. Being tanned with natural tannins, vegetable-tanned objects can be safely disposed of at the end of their lifecycle, thanks to their chemical-biological characteristics

Care instructions:

  • Wipe down the strap with a non-abrasive, lint-free cloth. If needed, you can lightly dampen the cloth with water. Leather straps are not sweat or water resistant. Soaking them will cause discoloration or other damage. Gently wipe away excess moisture with a dry, non-abrasive, lint-free cloth and let the strap air dry.
  • Direct sunlight, high temperatures, and humid conditions will cause discoloration or damage like hardening or cracking over time. Discoloration from wearing the strap is part of the aging of vegetable tanned leather.
  • To minimize discoloration and damage to these straps, limit exposure to moisture and substances like perfume, insect repellent, body oil or lotion, or dyed materials like denim.
  • For light-colored leather straps, minimize direct contact with dark-colored clothing, as color transfer may occur.
  • If you find flaking, cracking, or if the surface feels dry or hard, or if the leather has been soaked, you should treat the dry strap with leather balm suitable for vegetable tanned leather. Note that leather shoe cream is not suitable for this purpose. The leather balm will change the color of the strap, but this is part of normal aging.


Woven textile straps

Suunto Explore style textile straps are made of high-quality woven polyamide, and they are durable in use. Textile straps are ideal for outdoor sports and activities where the watch is worn over a sleeve since the material is very abrasion resistant. Textile straps also look good in everyday wear.

Suunto Athletic style braided textile straps are made of soft breathable stretchy material for great comfort and improved wrist heart rate measurement, making it
ideal for your sporty lifestyle and sleep tracking.

Unlike the leather straps, polyamide straps don’t mind if they get wet, but for the heaviest training or swimming, you should choose a silicone strap as it dries faster. Since polyamide straps are non-elastic, it may be difficult to tighten the strap enough for accurate wrist heart rate readings, and therefore a silicone strap is a better choice for measuring heart rate from the wrist.

Care instructions:

  • Like other textiles worn by you, your strap should be washed regularly with lukewarm water and mild soap.
  • Make sure to rinse the strap thoroughly after washing
  • Let it air dry properly before wearing it again. Direct sunlight, high temperatures, and constant humid conditions can cause discoloration or damage over time.
  • Use a soft-bristled toothbrush and water on persistent stains.
  • To minimize discoloration and damage to these bands, limit exposure to moisture and substances like perfume, insect repellent, oil, and lotion or dyed materials like denim.

It is also possible to wash the strap in the washing machine with similar colors, at low temperatures. Remove the watch strap from your watch and place it in a laundry bag to protect other clothing from the metal parts of the strap. Allow the strap to air dry after washing. Do not use a hair dryer or a tumble dryer to speed the drying, as high temperatures will damage the material.



Keep your watch clean

After each exercise, especially after swimming, wash your silicon, elastomer or nylon strap and the watch case under running, lukewarm water with mild soap to remove sweat and other debris to avoid skin irritation.

Keep your watch and wrist dry

Be sure that your wrist is dry before you put on your Suunto watch. After washing, dry it thoroughly before putting it back on your wrist.

Don't wear your watch too tight

  • Non-optical heart rate watches

Wear your watch loose enough so it can move back and forth on your wrist.

  • Optical heart rate watches

Give your skin a break

Wearing your watch long-term on the same wrist may irritate your skin. Let your skin rest on a regular basis, by taking your watch off or switching the watch to the other wrist.

Additional information

If you experience redness on the skin or some other irritation despite following the above tips and under normal conditions, remove your watch and let your skin recover. If the symptoms persist, consult a physician or dermatologist.

Please note: allergenic substances like fruit juice, raw potato, celery, albumen, corn, beans, peas, seafood, nuts, soy, wool etc., and abrasive substances like dust, sand and some skin lotions trapped under strap may cause severe skin irritation very quickly.
