What Will Happen If Your Watch Falls Into Seawater?

Watches are valuable accessories, often cherished for their functionality and style. But when a watch falls into seawater, a variety of damaging effects can occur, especially if it is not specifically designed for underwater use. Seawater is corrosive, and prolonged exposure can harm both the exterior and interior mechanisms of a watch. In this article, we’ll explore what happens to your watch when it encounters seawater and what you can do to minimize the damage.

Immediate Impact of Seawater on Watches

The main issue with seawater is its high salt content, which accelerates corrosion. When your watch falls into seawater, especially if it’s not water-resistant or specifically designed for such environments, the damage can start almost immediately.

1. Corrosion of Metal Parts:
   Seawater is highly corrosive to most metals, particularly if your watch is made of stainless steel, gold, or any other non-marine-grade metal. Saltwater can seep into the crevices and begin to corrode metal surfaces, leading to rusting, pitting, and permanent damage to the watch’s case, band, and clasp.
2. Damage to the Internal Mechanisms:
   If seawater penetrates the watch’s seals and enters the inner mechanisms, the movement and delicate components can be compromised. Salt particles can disrupt the fine gears and lubrication inside, potentially leading to the watch stopping altogether or erratic timekeeping.
3. Crystals and Gaskets:
   The crystal (glass) of the watch may experience clouding or damage due to exposure to the salt. The rubber gaskets, which are designed to keep moisture out, may degrade over time when exposed to seawater, compromising the watch’s water resistance further.
4. Impact on Non-Waterproof or Low-Water-Resistant Watches:
   If your watch isn’t water-resistant or only designed for minimal contact with water, exposure to seawater can result in almost immediate damage. Watches that are not equipped to handle the pressure or the salt content will likely allow water to seep in, causing serious harm to both the appearance and the internal workings.

What to Do If Your Watch Falls Into Seawater

If your watch accidentally falls into seawater, quick action is essential to reduce the damage. Here’s a guide on what to do:

1. Rinse the Watch with Fresh Water:
   As soon as possible, rinse the watch thoroughly with fresh water. This will help remove the salt particles from the surface and inside any crevices. Avoid using soap or other chemicals, as they can potentially do more harm than good.
2. Dry It Completely:
   After rinsing, make sure to dry the watch thoroughly using a clean, soft cloth. Pat the watch gently to remove as much moisture as possible. Avoid using a hairdryer or exposing it to extreme heat, as this could damage sensitive components inside.
3. Consult a Professional Watchmaker:
   If your watch isn’t designed for water exposure or if seawater entered the case, it’s important to take it to a professional watchmaker as soon as possible. They can open the watch, clean the internal components, and check for any signs of corrosion. Immediate servicing can help prevent long-term damage.

Prevention: Choosing the Right Watch for Water Activities

If you’re planning to spend time near or in the ocean, it’s a good idea to invest in a dive watch or a watch that is specifically rated for exposure to seawater. Here are a few features to look for in a seawater-friendly watch:

1. Water Resistance Rating:
   Watches rated for diving or swimming will usually have a water resistance of 100 meters or more. Look for watches with an ISO 6425 certification, as these are designed to withstand exposure to water and pressure at specific depths.
2. Materials:
   Watches designed for marine environments are typically made from corrosion-resistant materials such as titanium or ceramic. Marine-grade stainless steel and rubber straps are also commonly used to resist the corrosive effects of seawater.
3. Screw-Down Crowns and Case Backs:
   A screw-down crown and case back help create a watertight seal, preventing seawater from entering the watch. Watches with these features are better equipped for underwater adventures.

If your watch falls into seawater, corrosion and internal damage are the primary concerns. Rinsing it immediately with fresh water and drying it thoroughly can help prevent some damage, but professional servicing is often necessary.

To avoid these issues altogether, it’s best to wear a watch designed for marine use when around seawater. With the right precautions, you can enjoy your time by the sea without worrying about your timepiece.
