Handling Time
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
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.

Bought this watch a few months back, I don’t have the tools to size the bracelet but I finally got it sized and man I cannot take it off. After handling plenty of new and old Rolex’s, this is pretty dang close to what a 70’s - 90’s Rolex felt like. I set the watch three days ago and I noticed it has only gained 5 seconds since I last set the time. I don’t know if this modder regulates the movement but that it’s more accurate than all of my 4R36 movements in my actual Seiko watches. The only gripe I have was that I noticed an imperfection under the crystal, which Kool Mods have already agreed to fix and for that I can’t complain. Looking forward to buying more from this modder.
Will be ordering more in the future
I've been binge watching Magnum PI, and absolutely love this watch.
Great communication from the team at Kool Mods, and a very well-put-together watch.
Nice work!!
A slight. Error in my order was resolved easily, without stress and with great communication.
A lovely quality item. I’m very happy with my purchase.
