Our Best Sellers
Let's be clear
Not a replica. An original build.
A custom Chrono Mod copies nothing. It's an original design — inspired by the great classics of watchmaking, built as something entirely its own.
Our name on the dial
Every watch carries the Chrono Mod signature — never another brand's logo, never a protected design. What you wear is ours, and yours.
All-new parts, no donors
Cases, dials, crystals, movements: every component is brand new and hand-selected — nothing refurbished, nothing salvaged.
Built like it should be
Hand-assembled to order, individually regulated, water-tested and covered by a 2-year warranty.
Inspired by the classics. Signed Chrono Mod.

Got a question? We’ve got answers.
A Chrono Mod is a customized watch built using authentic Seiko movements and premium components. Each piece is individually assembled to reflect your unique style — combining precision, reliability, and creativity.
We use Seiko NH38, NH34, NH35, NH36, NH70, NH72 (automatic) and VK63, VK64 (mecha-quartz) movements — all renowned for their durability, accuracy and value. Every movement is tested before shipping.
Yes — our watches are water-resistant up to 100 meters, but only when using a solid stainless steel case back. This option ensures optimal sealing for everyday wear and even swimming.
If the model you're viewing doesn’t offer a steel case back by default, you can fully customize it using our configurator and select the steel case back manually. For best water resistance, avoid choosing the transparent sapphire case back.
Each Chrono Mod watch is hand-assembled and tested with care. Assembly takes 3 to 5 business days. Once ready, your watch is shipped and typically delivered within 8 to 12 business days.
The full process — from production to delivery — takes approximately 10 to 15 business days.
Yes. All orders include free worldwide shipping — no minimum purchase, no hidden fees.
No. We cover all customs and import fees for international orders. You will not be charged anything beyond what you pay at checkout.
You may return your watch within 30 days of delivery if:
- The item is not a custom-built model
- It is unused and in perfect condition
- It is returned in its original packaging
Please note: customized watches are not eligible for return unless there is a defect.
All Chrono Mod watches come with a 2-year warranty covering mechanical defects. If any issue arises due to assembly or component failure, we’ll repair or replace your watch at no cost.
Please note: the warranty does not cover accidental damage, water exposure if the case back is transparent, or normal wear and tear.
