Seiko Submariner Mod — choose your dial and bezel contrast

A Seiko Submariner Mod gives you a dive-watch silhouette with a dial and bezel combination you can choose for everyday wear. Start with a quiet black direction, the green dial and bezel of a Hulk build, or Kermit's green bezel around a black dial. The color pairing changes how much attention the watch draws while keeping the sports-watch shape at the center.

The design reference is the Rolex Submariner and the familiar visual language of dive watches. These are independent ModTime custom builds, hand-assembled to order; ModTime is not affiliated with Rolex or Seiko. The confirmed models here use an NH35 automatic movement with a date display.

Choose that movement when you want mechanical timekeeping and a date you can check alongside the time. The visual direction is a separate decision: a green bezel can frame a darker face, while a blue dial with two-tone accents can make the same sports-watch idea feel warmer and more expressive.

Compare the green Hulk and Kermit configurations first if color is your priority. For warmer contrast, open the two-tone Ocean or Root Beer build and study the actual dial and finish. Use the product photographs to compare the bracelet shape as well as the bezel, rather than choosing by the nickname alone.

The dive-watch inspiration describes the design. Water resistance is stated separately in the product options: standard 3 ATM and a paid 5 ATM configuration. Read the water-resistance guide before deciding how to use your watch, then choose your options and review the displayed price. For a travel-watch function, compare the GMT collection alongside these automatic date builds.

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.

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 ModTime custom watch unique.

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 FREE complimentary premium 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?

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.

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 Time 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 watch is hand-assembled within 4-6 days to ensure the highest quality and attention to detail.

Once completed, the shipping time is 7-12 days, depending on your location. While we aim for prompt delivery, some variations may occur based on the destination.

Please note: Due to the current global shipping conditions, especially related to parcel traffic in and out of the US, delivery times may occasionally be slightly extended. However, we do everything on our side to ensure the fastest possible handling and dispatch.

Please note that delivery times may vary depending on the destination country.

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.
