• Easy to install and replace — perfect for watch mods and small batch productions

Compatible With Other Movements:

Seiko NH36: Structurally identical to the NH35, the only difference is that the NH36 includes a day display in addition to the date.

Seiko 4R35: NH35 is the export version of the Seiko 4R35. Functionally and dimensionally identical. Hands, stem, dial feet, case fitting – all compatible.

Seiko 7S26 (partial compatibility):

• NH35 is often used to upgrade watches with 7S26 (like old Seiko 5 models).

• Case size and dial feet may match, but:

  • 7S26 doesn’t have hacking or hand-winding

  • Stem height might differ, so slight modification may be needed.

Miyota 8215 / 8205 (NOT directly compatible):

• Though often compared with NH35, they are not directly interchangeable:

  • Different dial feet positions

  • Different stem height and case tab location

  • Crown position may need adjustment

• Only some aftermarket cases are designed to support both.
