Handling Time

As each watch is custom built to order, please expect a 2 to 4 week build time. We try to turn around under the handling time but occasionally delays can occur.

Water Resistance

A watch that is water-resistant to 5ATM (50 meters or 165 feet) can handle more than just occasional splashes of water. However, to ensure your watch remains in optimal condition and retains its water resistance, proper care is essential. Here’s a comprehensive care guide to help you maintain your 5ATM water-resistant watch.

Understanding 5ATM Water Resistance

Before diving into the care instructions, it’s important to understand what 5ATM water resistance means.

  • 5ATM indicates that the watch can withstand water pressure up to 50 meters deep.
  • This rating is suitable for light water activities such as swimming in shallow water.
  • It is not suitable for diving, snorkelling, or any high-pressure water activities.

Do Not Wear Your Watch in Showers

Avoid Hot Water: Do not wear your watch in hot showers, saunas, or hot tubs. The heat can cause the seals to expand and contract, compromising the water resistance. This can cause your watch to fog.
