Seiko Mod Gift Guide: Watches & Kits by Budget
In This Guide
Buying for someone who's into watches — or someone you suspect would be, if they had the right first piece? A Seiko mod is a genuinely good gift: a mechanical watch with a sapphire crystal and a real Seiko automatic movement inside, in a design that nods to the icons, for a fraction of what the originals cost. This guide sorts our in-stock gifts by budget, so you can skip straight to your price range. Everything below is in stock as of this update.
Under $40 — for the modder who already tinkers
If they already own a build and love swapping parts, these are the stocking-stuffers. All of them fit the standard NH35-family platform (NH35/NH36/NH38/NH70/NH71/NH72), so you don't need to know exactly what's on their bench.
| Gift | Price | Why it's a good gift |
|---|---|---|
| Extended Link – Royal Oak | $15 | Adds a link for a larger wrist — the quiet fix most Royal Oak builders end up needing. |
| Royal Oak Hands (V1 / V2) | $28 | A fresh hand set in silver, gold or rose gold instantly changes a dial's character. |
| Waffle Dial 28.5mm | $29 | Textured waffle dial in several colours — an easy, forgiving dial swap. |
| Spare Caseback – Royal Oak 37mm | $30 | Our most-reviewed small part (72 reviews). Swap to a display caseback to show the movement. |
| Nautilus Dial 30.8mm | $32 | Sunburst-texture dial for Seikonaut and 30.8mm builds. |
| Royal Oak 41mm Rubber Strap | $39 | A sporty strap option for the 41mm case — changes the whole feel in seconds. |
| Royal Oak Skeleton Dial V2 28.5mm | $40 | Open-worked skeleton dial in silver, gold or rose gold. |
$110–$195 — start a build (cases & movements)
For the person who wants to make something. Pair a case with a movement, a dial and a set of hands and they've got a weekend project that ends in a watch they built themselves. Everything here is designed for the NH35-family of Seiko movements.
Cases
| Case | Price | Notes |
|---|---|---|
| Royal Oak 41mm Case | $110 | Our most accessible integrated case. Takes 30.8mm dials. 23 reviews. |
| Royal Oak 37mm V2 Case | $149 | The one everyone starts with — slim (11.2mm), sapphire, integrated bracelet. 72 reviews. |
| Seikonaut 40mm Case | $149 | Ultra-thin integrated sports case. Takes 30.8mm dials. |
| Petrichor 37mm Case | $195 | Our own original design — for someone who wants something that doesn't reference an existing watch. 9 reviews. |
Movements (Seiko automatic)
| Movement | Price | Best for |
|---|---|---|
| NH35 | $130 | The default — date at 3, hacking + hand-winding. Best all-rounder. |
| NH36 | $140 | Day-date complication. |
| NH38 | $140 | Clean no-date dial layout. |
| NH71 / NH72 | $140 / $150 | Skeletonised — finished to be seen through an open-worked dial. |

$250 — the showpiece: turn a MoonSwatch into steel
If they own an Omega × Swatch MoonSwatch (a "Royal Pop"), our AP × Swatch Royal Pop conversion case ($250) rehouses it in a proper stainless-steel case with a sapphire crystal — a real wrist-ready watch instead of bioceramic. It's our single most popular product, and the gift that gets the biggest reaction.
$350 — a finished watch, no tools needed
Don't want to hand someone a box of parts? These are complete watches — professionally assembled, regulated and pressure-tested, with a sapphire crystal, a genuine Seiko automatic movement and an integrated bracelet. Luxury-inspired design, ready to wear out of the box, all $350.
| Finished watch | Price | Reviews |
|---|---|---|
| Royal Oak 37mm / 37mm Skeleton | $350 | 72 |
| Royal Oak 41mm Skeleton | $350 | 23 |
| Nautilus 40mm / Nautilus Skeleton | $350 | 6 |
| Petrichor 37mm / Petrichor Skeleton | $350 | 9 |

Not sure which to pick?
Two easy rules. If they like building things, a case + movement + dial + hands from the $110–$195 section is a project they'll love. If they just want a great watch, give a finished $350 build and let them wear it the same day. And if you genuinely can't call it, a Nomods gift card lets them choose their own.
Shipping for Christmas: order early — we'll post the exact "order by" cut-off date closer to December so your gift arrives in time.
Gift FAQ
What's the best Seiko mod gift for a beginner?
If they don't want to build anything, a finished $350 watch (the Royal Oak 37mm is our most-reviewed) is ready to wear. If they'd enjoy the project, start them with the Royal Oak 37mm V2 case, an NH35 movement, a dial and a hand set.
Do they need tools?
Finished watches: no — they're assembled and ready. Cases, movements, dials and hands: yes, a basic hand-press and movement holder. Our build guide lists exactly what's needed.
Will the parts fit any Seiko?
Our cases, dials and hands are built for the Seiko NH35-family of movements (NH35, NH36, NH38, NH70, NH71, NH72) and compatible 4R-series calibers. They're aftermarket mod parts designed to fit that platform — check the movement your recipient uses before mixing brands.
Can it be returned?
Yes, per our standard returns policy. Finished watches and unused parts can be returned — see the returns page for the window and details.
Nomods is not affiliated with Seiko, Audemars Piguet, Patek Philippe, Omega or Swatch. All watches are independently built using Seiko-compatible movements and aftermarket components.
