Seiko Mod Hands, Lume and Fauxtina Buying Guide

How to choose Seiko mod hands for NH35 builds: hand tube sizes, hand styles, lume matching, fauxtina color, clearance checks, and common buying mistakes.

·7 min read·Assemble Watches Editorial

Hands are small, but they can make or ruin a Seiko mod. They need to fit the movement, clear each other, suit the dial, and make sense in low light. Lume color is not a detail you fix at the end; it is part of the design from the start.

If you are choosing hands for an NH35 build, pair this guide with the NH35 dial guide and preview the combination in the builder before ordering. Transferring hands as part of a 7s26 to NH35 movement swap? Fit a fresh handset rather than reusing stretched originals.

Hand fitment basics

HandNH sizeWhat to check
HourAbout 1.50mmSits low, so check dial clearance first.
MinuteAbout 0.90mmMust clear the hour hand through 12 hours.
SecondsAbout 0.20mmEasy to bend and easy to set off-level.

The correct tube size gets the hand onto the movement. Good installation keeps it level once it is there.

Choosing hand styles

StyleWorks well withWatch out for
BatonModern divers, field builds, clean dialsCan look plain on a dramatic dial.
DauphineDress and Grand Seiko-inspired buildsNeeds a dial with enough refinement.
MercedesVintage diver and Sub-inspired buildsVery recognisable, so it can dominate the design.
ArrowTool watches and explorer-style buildsLarge tips need careful clearance checks.

Lume matching

Lume matching is mostly about temperature. White lume reads modern and clean. Cream or beige lume reads vintage. Green-tinted lume can work on divers but may clash with warm fauxtina markers. The dial, hands, and bezel pip should look like they belong to the same watch.

Also check the amount of lume. Thin dress hands on heavy diver markers can look weak at night. Huge diver hands on a minimalist dial can look blunt. Daytime proportion matters as much as glow.

Buying fauxtina parts without making a costume watch

Fauxtina works when it looks like a design choice, not a filter applied to every part. A warm dial with matching warm hands is enough for many builds. Add a faded bezel insert only if the case shape and crystal profile also support the vintage look.

For a first vintage build, avoid mixing several unrelated aging tones. Cream hands, orange markers, and a green bezel pip rarely look naturally aged together. Pick one warmth and keep it consistent.

Frequently asked questions

What hand sizes fit the NH35?

The NH35 uses standard Seiko NH hand sizes: about 1.50mm for the hour hand, 0.90mm for the minute hand, and 0.20mm for the seconds hand. Buy hands listed for NH35, NH36, or SKX-compatible builds and verify the vendor spec if the listing is vague.

What is fauxtina lume?

Fauxtina is modern lume colored to look aged, usually cream, beige, or warm yellow. It gives a vintage look without actual radioactive or degraded old lume. It works best when the dial markers, hands, and bezel pip share a similar warmth.

Should the hand lume match the dial lume?

Usually yes. Slight contrast can look intentional, but bright white hands on warm fauxtina markers often look accidental. If the dial has aged lume, choose hands with warm lume or a metal finish that makes the mismatch feel deliberate.

Why do my hands touch after installation?

Hands touch when one is pressed too low, tilted, or not seated level. Check from the side with a loupe, then advance through 12 hours before closing the case. If a hand is bent or the tube is damaged, replace it rather than forcing it.

Preview hands and dial together

The easiest way to spot a mismatch is to see the dial, hands, case, and bezel together before ordering.
