Most NH35/NH36 dials mount directly. Some cases require repositioning or trimming; check each product’s fit notes.

Use NH-series hands (e.g., 150/90/21 or as specified). Always confirm hand hole sizes in the listing.
30.8 mm Dials
Which cases need 30.8 mm dials?+
Royal Oak 41 mm and Aquanaut-style 39–41 mm builds generally require 30.8 mm dials.
Do 30.8 mm dials still use NH35/NH36?+
Yes—most use NH35/NH36. Some are also compatible with NH7x skeleton movements; check the fit notes.
Anything special about crystals here?+
Larger dial windows often pair with taller or domed sapphire. Verify crystal height/profile per case.
