YOUR WATCH, YOUR STYLE

A SEIKO Mod watch is a customized version of a standard Seiko watch. The term "MOD" comes from "modification". These modifications are generally made for those who wish to personalize their watch according to their specific tastes or needs. Modifications can vary considerably, from minor aesthetic changes to more complex technical revisions. What makes SEIKO watches particularly amenable to modification is the wide availability of spare parts. This abundance of components enables a wide range of customization, making each SEIKO MOD watch unique.

Each custom timepiece is hand built in United-Kingdom, To ensure the highest possible standards, we have a lead time of 7-10 days from the date of order to delivery. This allows us to carry out the necessary quality control procedures and ensure that your watch is made to your satisfaction.

All orders placed through our website are subject to the given lead time even if the item is shown as "In stock".

Each watch is assembled by hand piece by piece in a completely handmade way by an expert with more than 4 years of experience.

We use Japanese movements, especially SEIKO automatic movements, which are celebrated for their dependability, accuracy, and long-lasting performance.

Movements we use at Perpetual Precision:

NH34-NH35-NH36-NH38 Automatic Movements

Our watches are designed with a water resistance rating of 5 ATM, which makes them suitable for everyday use and able to withstand splashes or brief immersion in water.

However, they are not intended for swimming or taking baths.

To ensure the longevity and optimal performance of your watch, we recommend avoiding prolonged exposure to water.

We use premium 904L stainless steel, scratch-resistant sapphire crystal, and high-quality leather or silicone straps for lasting comfort and durability.

An automatic watch is powered by the natural movement of your wrist — no batteries required. It’s a precise mechanical timepiece that combines durability, craftsmanship, and timeless style.

To keep your automatic watch in perfect condition, avoid strong impacts, clean it regularly with a soft cloth, and have it professionally serviced every 3–5 years.

Automatic watches are powered by a precise mechanical movement and the natural motion of your wrist, while quartz watches rely on a battery. Automatic timepieces are known for their craftsmanship, longevity, and appeal to collectors.
