Maintenance and care


Every watch needs little attention and a minimum of care, like everything we care about.

Watches by Fonderia, with their hand-crafted soft vintage leather straps, are made to be at their best only by living at your wrist, day after day, maturing with you, sharing your experiences and your adventures.

The watches, made exclusively in steel, will need little care, that you can find described in the sections below.

Water Resistance

Some materials are water resistant, so they are not permeable to a fluid. In the case of watches, it is the resistance, expressed in atmospheres (ATM), that the watch opposes to the pressure exerted by a fluid.

For maintaining your watch’s ability to resist water for as long as possible, the seals of the following components must be checked every two years: glass, back and crown.

We must be very careful with the watch crown: it must always be correctly positioned, either screwdown or push button crown depending on the model, thus blocking the entry of water into the movement.

Fonderia watches are resistant to water pressure up to 30 meters (3 ATM pressure resistance), 50 meters (5 ATM), 100 meters (10 ATM), 200 meters (20 ATM) depending on the type of model. It is important not to adjust the crown or press the buttons (if any) to activate functions when the watch is in water, as the water can penetrate the case. It is not recommended to use the watch in hot water or water vapor (shower and sauna) as the seals may be damaged. Finally, it is not recommended to dive into the water wearing the watch as it  could lead to shocks, damaging the watch.

Battery life in case of quartz movement watches

Quartz  watches battery generally can last between 1 and 2 years.  When the watch stops, you need to replace the battery in a specialized center.

Mechanical movement watch

An automatic mechanical movement watch harnesses energy through the natural motion of the wearer’s wrist. A manual winding watch, after being manually loaded by turning the crown 20 times clockwise, has a power reserve of approximately 30 hours without being worn. Therefore the watch has to be manually loaded by turning the crown clockwise for about 20 turns. If you're not wearing your watch for a long time, it is recommended to charge it regularly, once a month to prevent the lubricant inside the movement from thickening and to keep the watch away from moisture and dust.

Set the date

In mechanical watch with date, you should not set the date when the time on the watch reads between the hours of 9:00 pm and 3:00 am to avoid damage to the date sprockets.

Daily care


Every time you immerse the watch in salt water or in water containing chlorine, then wash it in fresh water, removing any foreign material with a soft brush (or a soft cloth).

Sterling silver is a beautiful and durable metal that is made for everyday wear.  Following a few basic use and care guidelines will ensure that your sterling silver items give you a lifetime of enjoyment. 
Please keep in mind that detergents can slowly erode the finish of gemstones and cause stones to become dull. Keep sterling silver and precious gemstones away from chlorine bleach and all household cleaners. These will cause damage to the silver and stones. Keep them away from sulfur baths (SPA) and pay attention to perspiration resulting from an acid skin Ph that could accelerate oxidation.
Jewelry should always be removed before swimming and washing dishes. Sterling silver is not difficult to take care of if you just follow a few simple precautions: 
Storing your sterling silver jewelry
Storing sterling silver in the open air and humidity for extended periods of time can cause it to tarnish quickly. Tarnish first appears as a golden hue on sterling silver, then quickly turns to black. This is a normal process that is caused by oxidization and moisture from air and sunshine. 
To reduce tarnish and keep jewelry tarnish free, it is recommended that sterling silver jewelry be stored in an air-tight protective bag with a tarnish proof Polishing Cloth.
Although sterling silver jewelry is scratch resistant it isn’t scratch proof, so it is recommended that jewelry be stored so that it isn’t rubbing up against other articles, like in a loose drawer or jewelry box.  
Cleaning your sterling silver jewelry
Clean sterling silver jewelry with a Polishing Cloth and gently rub off any excess dirt or makeup. Sterling silver is a very soft metal and can be scratched if it is rubbed too briskly.
We hope that these guidelines will allow you to maintain and enjoy your sterling silver items for many years to come!
