Seiko Instruments (SII) NH36a movement with fine finished rotor. Black 3:00 crown day/date. JAPAN stamped on rotor at 12:00 - same temporary stem with green winding crown as Japan made NE15. Movements without the Japan stamp are not made in Japan, despite claims to the contrary. Choice of regulated or unregulated.
Usually ships within 2-3 business days. Regulation may add 2-3 business days.
*SKX007/9 and other 3:48 crown location watches will need an appropriate day wheel for the day to align correctly. AHW does not currently stock these parts for sale.
**SKX007/9 and other Seiko watches with screw-down crowns will require a new crown that will accept the threaded stem, which must be trimmed to fit. The stock crown is not able to be disassembled. AHW crowns are available for purchase.
***Care must be used to ensure the stem is trimmed long enough for proper function.
****Base movements are unregulated- just as they come from the factory. The movements are function tested before shipment.
*****Regulated movements are now being offered. Regulation may add several days to the ship time.
THE END USER IS RESPONSIBLE FOR THE CAREFUL INSTALLATION OF HANDS AND DIAL. MANY DIY WATCH BUILDERS HAVE RUINED MOVEMENTS DURING THIS PROCESS, AND/OR REGULATION ATTEMPTS. AHW IS NOT RESPONSIBLE FOR ANY DAMAGE TO MOVEMENTS DUE TO THESE PROCESSES.
