Frequently Asked Questions

What is a custom ModTime watch?

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.

Which movements do we use?

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.

Can I adjust the watch size myself?

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.

Can I choose a clean or dial-marked version?

Use the LOGO / NO LOGO selector on this product page before adding your watch to the cart. Check the selected option in your cart before checkout.

Can I design my own watch?

Can I design my own watch?

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.

If you’d like to design a fully personalized ModTime piece, simply reach out to us on WhatsApp. Our watchmakers will guide you through every step of the customization process — from concept to final assembly.

Shipping Times and Costs

Free tracked shipping to the US. Import costs are included; there are no import surcharges on delivery. See checkout for the final order total.

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.

Are the watches water resistant?

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.

No answer matches that yet. Try a broader word — or reach our watchmakers on WhatsApp and we’ll help directly.

BUILD STORY

Materials and function of this build

NH38 no-date automatic. Wrist movement winds the mechanical movement. This no-date configuration keeps the time display free of a date window. Where this version has an open-heart or skeleton dial, that opening is a view of the mechanics rather than an additional timing function.

Choose this function when an uninterrupted dial or a view of mechanical movement is your priority.

This version: SANTOS WATCH MOD SILVER WHITE DIAL. Compare this version’s dial and finish in the product photographs, then select the configuration on this page. Listed case size: 38 mm.

904L stainless-steel case: a corrosion-resistant case material. This specification refers to the case, not automatically to every bracelet or clasp component. The finish colour is a separate feature, and steel can still show wear.

Sapphire crystal: highly resistant to surface scratches, helping keep the dial readable. Sapphire can still chip or crack under impact; the material name alone does not imply an anti-reflective coating.

Explore the 904L case material, sapphire crystal and NH38 no-date automatic function guide before choosing your build.

A white dial with dark Roman numerals sits inside a square silver-tone case with rounded corners. The product photograph shows dark hands and visible screw details around the bezel and along the bracelet, giving this ModTime Santos-style custom watch a different outline from the round-case designs.

Choose this configuration if case shape and a light dial are your starting points. Compare the corners, bezel width and bracelet attachment in the photograph rather than comparing diameter alone with a round watch.

Review the dial-marking and water-resistance options before ordering. The selected configuration should match the build you intend to buy.

This no-date Santos-style build uses an NH38 automatic movement. Its 38 mm square case and uninterrupted Roman-numeral dial offer a different shape and layout from the round Datejust-style watches with a date window.
