Watch-Modz review 2026

Watch-Modz is a strong one-stop shop for Seiko modders building on the SKX007 platform with NH35/NH36 movements, from sterile dials to sapphire crystals and complete cases. Skip it if you have never modded a watch and don't plan to use a watchmaker, since the store itself recommends professional installation. Confirm movement and case compatibility on every part before you order, because returns must be unused and you pay return shipping.

About Watch-Modz

Watch-Modz sells aftermarket parts for Seiko-style watch mods, mostly built around the SKX007 case format and the NH35, NH36 and NH38 movement families. According to its About page, Watch-Modz LLC is an independent US company founded in January 2021 by Delbert Duba III, who is legally blind and built the brand around his passion for modding. The site also points customers to a Facebook group for watch modders.

Catalog and prices

The store lists 537 parts, with a median price of $29.99. That covers nearly every component you need for a build: bezels and bezel inserts (82 each), hands (76), dials (58), chapter rings (48), straps (39), cases (38), movements (23), case backs and crowns.

Smaller parts are inexpensive. Single second hands like the NH35 Hand: Orange Milguass are $12.99, chapter rings such as the Polished Rose Gold W/ Minutes are $19.99, and sterile NH35 or NH36 dials start at $19.99. Engraved SKX007 case backs (Snake, Zombie, Japanese Building) are $23.99 and are listed as 316L stainless steel with 200M water resistance and a gasket included. Bezel inserts are $29.99, and full bezels $35.99.

Bigger upgrades include SKX007 sapphire crystals ($39.99 to $46.99, including a blue AR option with a date magnifier), the NH71 skeleton movement ($94.99) and complete cases. The SKX007 Case: Black MM300 3:00 is $69.99, the Black Racer case is $79.99, and the Silver PRX case, which includes a sapphire and bracelet, is $119.99. There is even a $19.99 DIY digital watch kit for beginners who already own a soldering iron.

Many parts are styled after well-known luxury and tool watches, such as Nautilus-inspired hands, Oyster Perpetual-inspired dials and a MarineMaster-style case. These are homage parts for personal builds, and sterile dials are sold specifically so you can add your own logo. Only 18 items are on sale.

What to know before you mod

The FAQ recommends that all modification work be done by a professional to avoid damaging your watch. Parts are listed for specific movements (NH35/NH36 versus NH38) and specific case formats, so double-check the listing before mixing components. Dial diameters, such as 28.5mm, are given on many dial pages.

Tips before you buy

  1. Match every part to your movement (NH35/NH36 vs NH38) and case format before ordering
  2. Check dial diameter and date window position against your case and chapter ring
  3. Have a watchmaker install parts if you're new to modding, as the store's FAQ recommends
  4. Don't test-fit a part you might return, since returns must be unused
  5. Buy sterile dials if you want to add your own logo
