Modern Parts Compatibility for Seiko Modernistic

What part tin exist used to mod a Seiko dive sentry

Our dive watch is designed with compatible parts with Seiko watches

Our dive lookout is designed with compatible parts with Seiko watches

Nosotros designed our DIY diver watch so that some of our part are compatible with Seiko swoop watches (SKX007/SRPD). These parts are therefore interchangeble betwixt our dive sentry and Seiko scout. That means you lot can employ these parts from our dive lookout man to modern a Seiko sentry, or apply parts from a Seiko picket to mod our dive watch.

Which Seiko sentry is compatible?

SKX series (namely SKX007 and its variants), which is one of the most modded watches in the modern watch community, is uniform with our swoop sentry.

Left: Seiko SRPD / 5KX; Right: Seiko SKX. These watches accept uniform parts with our dive watch

In addition, the new Seiko 5 Sports serial (SRPD), nicknamed "5KX" precisely considering information technology shares many similar parts with the SKX serial, is uniform as well .

Other popular Seiko mod watches, such equally SNZF urchin and SRP turtle, are compatible only nether specific conditions (such as matching movement, punch size, and crown position, see below for detailed breakdown) and the possible modification is limited at all-time. Therefore, modding of these watches is best reserved for the experienced modders.

That said, here is a list of uniform parts and non-compatible parts for SKX and SRPD Seiko watches:

Uniform Parts

  • Easily

    The movement of our dive picket is pretty much the aforementioned as that of Seiko SKX and SRPD series (see below for a breakdown between 7s36, 4r36, NH35/36, and NH70/72), the simply difference between them being date band vs day/engagement ring. Therefore the hands of our dive lookout and those of Seiko SKX/SRPD are interchangeble, also as those of other Seiko watches using 7s35/36 and 4r35/36 movement.

  • Bezel

    All of our bezels are interchangeble with Seiko SKX and SRPD bezels. One point of note though: the bezel insert must be changed in tandem with its bezel, i.e. you lot tin apply our bezel insert along with our bezel onto a Seiko, but you cannot apply our bezel insert to a Seiko bezel. If you want to do a bezel modern, check out our quick guide on changing bezel.

Semi-uniform Parts

These parts are compatible simply nether specific conditions, and might require advanced modding techniques:

  • Straps

    Our dive scout has a lug size of 22mm, which is the same as that of SKX and SRPD. Merely at that place is one major difference between SKX and SRPD: the springbar of SKX has a thicker diameter and tip (which is why the Seiko modernistic community affectionately calls information technology the "fat springbar"), significant that our straps are non directly interchangeble with SKX straps. One exception is our parachute strap, which tin can be used on an SKX watch by keeping the SKX's original "fat" springbar.

    On the other manus, the springbar of Seiko SRPD has a smaller tip which is the aforementioned size as ours, and therefore our straps tin can exist used on SRPD watches, and vice versa.

    Please annotation that some after-market straps take special shapes and structure (like curved end designed to taper fit with the case). Therefore compatibility of these straps are non guaranteed.

  • Dial

    The SKX and SRPD have a 4 o'clock crown, while our dive watch has a iii o'clock crown. This means that unless without extra modding, the dials are not compatible.

    For the experienced modders though, the dials are of the same size, so information technology is possible to use our dial on Seiko (and vice versa) past either modding the position of the dial feet, or cutting the dial feet off and attaching it to the movement using other means.

    If you're looking for other aftermarket dials, check for these points: i. dial size (28.5mm); 2. crown position; three. solar day/appointment window or date window.

  • Movement

    For the uninitiated, offset, a quick summary of the many confusing model numbers of Seiko movements used in SKX and SRPD watches:

    • 7s26 is the move used in SKX007, and 7s36 is the 7s26 update with 2 extra non-functioning jewels.

    • 4r36, used in SRPD, is the modern upgrade of 7s26/36 with manual winding and hacking second.

    • NH36 is the unbranded version of 4r36. And NH35, used in our dive watch, is the variant with just date ring (the 7s36 and 4r36 have a date /day ring, meaning it shows both 24-hour interval of the week and the date of the month)

    • NH70 and NH72 is the skeleton dial variant of the basic NH movement. They feature a remainder wheel at nine o'clock. Construction is almost the aforementioned except they need a motility holder change to fit the usual Seiko mod.

    Another signal to observe is that the SKX and SRPD feature a iv o'clock crown, therefore when used on a 3 o'clock crown dial and instance (like ours), the mean solar day will exist shown as clipped by the dial window, simply the date volition remain fine.

    This ways that: ane. the movement of SKX and SRPD can be used in our dive lookout man, given that you either give it a dial with a date-but window, or replace the day ring with a three o'clock version and couple it with a dial of 3 o'clock dial feet; ii. the movement can be used on SKX and SRPD if used together with a dial with date-only window and 4 o'clock punch feet.

Special case with non-SKX/SRPD Seiko watches

Seiko watches which have the same movement (7s or 4r equivalent), dial size (28.5mm), and crown position (3'o clock) every bit ours can take their move assemblies (i.east. movement with dial) installed directly into our instance past using our move holder and chapter ring. A skilful example is SNZF Urchin. Encounter case below:

Non-uniform Parts

  • Crown

  • Instance back

  • Crystal

  • Affiliate ring

  • Bezel Insert (unless coupled with our bezel)

  • Gasket
