ROYAL OAK CHRONOGRAPH WATCH MOD BLACK BLUE DIAL

A ModTime custom watch is an independently assembled watch built from compatible components around a chosen movement, case, dial and bracelet.

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.

ModTime custom watches are independently assembled around compatible components and selected specifications. ModTime is not affiliated with, endorsed by, or an official service provider for any OEM or luxury watch brand.

At ModTime, we work exclusively with reliable, high-grade Seiko movements — trusted by watch enthusiasts worldwide for their precision and durability.

Each movement is carefully selected and tested by our watchmaker to ensure optimal performance and a smooth mechanical experience.

We use:

• NH34 Automatic — for our GMT Mods
  
• NH35 Automatic — for date dial builds
  
• NH38 Automatic — for clean dial designs without a date
  
• VK63 Mecha-Quartz — for chronograph models

Every ModTime watch is powered by a movement chosen for its accuracy, longevity, and craftsmanship — the foundation of every timepiece we create.

Absolutely! Every ModTime timepiece comes with a complimentary adjustment kit, allowing you to resize your bracelet easily and safely at home.

Each tool is designed for precision and comfort — the same way our watches are crafted.

If you prefer, your local watchmaker can also assist you with the adjustment — our bracelets use standard Seiko-compatible links, making professional resizing simple and effortless.

Yes — absolutely! Every ModTime timepiece can be fully customized to match your personal vision.

If you prefer a clean, minimalist dial without visible dial branding, our watchmakers will assemble your piece accordingly during the hand-crafting process.

Simply include your preference in the order notes at checkout, and we’ll ensure your watch is built exactly the way you want it — refined, personal, and uniquely yours.

Absolutely. At ModTime, every timepiece can be crafted to your personal vision — from the bracelet and case to the dial, hands, and finishing details.

You can even add your own logo or initials, turning your watch into a truly one-of-a-kind creation.

Each custom watch is hand-assembled to order. Typical assembly time is 4-6 business days.

After dispatch, delivery usually takes 7-12 days depending on destination, carrier flow and customs handling.

You will receive order support from ModTime if anything needs clarification before or after dispatch.

ModTime watches use variant-dependent water-resistance options such as 3 ATM or 5 ATM. 3 ATM is intended for daily splashes and rain. 5 ATM gives more everyday margin, but custom watches should still be kept away from swimming, bathing, diving and prolonged water exposure unless a specific model is explicitly rated for that use.
