How to Clean a Soft Leather Watch 
Avoid heavy duty leather cleaners
If you have a soft leather watch, it’s important to keep it clean and dry. Avoid using heavy duty leather cleaners, as these can weaken the leather and make it look unattractive. Instead, use a soft, lint-free cloth to clean the strap of your watch.
If you don’t know how to clean leather, you can use hydrogen peroxide. It works by quickly oxidizing mold and decomposition. It also foams, helping to lift the mold away from the textile. However, this chemical will cause bleaching, so be careful! Over-the-counter hydrogen peroxide will have the least bleaching risk. Laboratorial-grade and janitorial-grade hydrogen peroxide may bleach the leather, so you should always wear chemical-resistant gloves when using this solution.
To clean a soft leather watch, use a soft cloth or brush. Be sure to wring out the cloth completely after cleaning it. Do not use regular soap or abrasive cleaners. These can cause discoloration and dry the leather.
Avoid reattaching leather watch straps while it’s wet or damp
Leather watch straps require special care and should not be reattached while wet or damp. Leather can be fragile and crack easily. This is why it is important to use a good conditioner. Some high-end watches are designed to withstand all kinds of weather.
When cleaning your watch, remove the strap. Using a microfibre cloth, wipe the leather gently. This will prevent it from scratching. You can also use a soft, unused toothbrush or a soft cloth to scrub away dirt from the strap. After cleaning, pat the strap dry with a soft cloth or an old T-shirt.
Keeping your watch clean will help it last a long time. Taking care of your watch will help it last longer and continue to give you great service. This will prevent you from having to buy a new one too soon.
Avoid drying leather watch straps before going to bed
Leather watch straps are susceptible to stains and smells if exposed to water. To prevent this, remove your watch before going to bed, swimming, and working out. If it does get wet, dry it in the shower with a paper towel. Never use a blower or the sun to dry it. This will cause the leather to become cracked.
Leather straps require special care, and it is important to use the proper conditioner to keep them from drying out. Even the highest quality watches can crack and dry out if they are not treated properly. If you want to keep your leather strap looking new, make sure to purchase a high-quality watch with a water-resistant strap.
When washing your leather watch straps, be sure to rinse them thoroughly before applying them to your watch. This is important because leather can become damp and absorb sweat and dirt. This causes the straps to absorb smells and can cause them to stretch. Avoid leaving your leather watch straps wet when going to bed.
Avoid reattaching spring bar pins while it’s wet or damp
Before you can begin re-attaching spring bar pins, make sure that the watch is dry and free of any liquid or other substance. You may need to repeat the process if the spring bars are thick and hard to remove. After you have removed the spring bars, you can insert the strap-changing tool into the lug hole. Insert the tool until the spring bar pops free of the lug. Do not force the spring bar back into the watch; it could scratch the lugs. Practice will make this process easy.
First, clean the strap with a soft, clean cloth. Using a mild soap or cleaning agent, clean the strap thoroughly. Be sure to replace the cleaning cloth afterward. Next, condition the leather strap before re-attaching the spring bar pins. Conditioning the leather adds a protective layer to the watch and helps it resist moisture.
Re-attaching spring bars is similar to re-attaching the lugs, but requires a bit more care. If the spring bar is not seated properly, the watch may fall off the wrist.
