Buying from Watch-Modz

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.
