One of the main differences between the two is their beat rate. The Seiko Nh35a and Miyota 9015 are two of the most popular Japanese automatic movements.

Miyota 8215 // Source: Rosstomson NH35a vs Miyota 9015 Both are widely used in many microbrands and entry-level watch mods. The Miyota 8215 is known as a great entry-level workhorse movement that is reliable but suffers from faults such as an excessively loud rotor. The NH35 is slightly more expensive, but is said to be a bit more reliable than the Miyota 8215, and has a few extra features in its hacking and hand-winding. The NH35 and Miyota 8215 movements are two of the most popular affordable Japanese automatic movements. The NH35a and 4R35 are essentially the same build, with the same accuracy, specifications, and etc. Along with the 4R36 movement, the 4R35 is the primary modern movement Seiko uses in their entry-level Seiko 5 Sports models. The NH35a is essentially an unbranded Seiko 4R35 movement. NH35a vs Seiko 4R35 Seiko’s 4R36 movement, similar to the 4R35 and NH35a, with the addition of a day (instead of just a date) complication The NH35, like the Seiko branded equivalent, the 4R35, has hacking and hand-winding, while the 7S26 does not.

The NH35 is essentially an unbranded upgrade of the Seiko 7S26 movement. The only difference is the NH35a only has a date complication, while the NH36a has day and date. The NH35A and NH36A are both based on the Seiko 4R family of movements. Rotate the crown counter-clockwise, toward you, until the proper date is set.Ensure the crown is in position 1, pulled just one click away from the watch case.Push the crown back down to position 0, toward the case.Rotate the crown freely, clockwise or counter-clockwise, until the hour and minute hands are in the correct place.Ensure that the crown is in position 2, pulled all the way, two clicks away from the case.

The rotor will constantly rotate, winding the mainspring with each rotation.

Rotate the crown for 55+ full rotations to fully charge the 41-hour power reserve.īecause the NH35 has an automatic mechanism, it is not possible to overwind, and exceeding the suggestion of 55+ rotations will not damage the watch.įurther, the rotor in the automatic mechanism will continue to wind the mainspring, and power the watch, while it’s on the wearer’s wrist.

Rotate the crown clockwise (forward, if the watch dial is facing you).

Ensure that the crown is in position 0 (pushed in toward the case).

Winding the mainspring, and charging the power reserve of the NH35 is simple. The rotor will have inscribed ‘Japan’ or ‘Malaysia’ depending on its country of manufacture. From the factory, they can be easily distinguished by checking the engraving on the automatic rotor. The NH35a has two variations, manufactured in either Japan or Malaysia. Manufacturing Variations: Japan and Malaysia Its reliability, for such an affordable movement, is one of the reasons it is so highly regarded. The NH35 movement is a reliable, workhorse movement that is not known to have any recurring issues. This is due to the inclusion of plastic parts which reduce the need for frequent lubrication for maintenance. The NH35 is based heavily on the workhorse Seiko 7S26 movement which is known to last upward of 5-25 years without ever needing a service. However, most NH35 owners find their movements to run much more accurately, often between -/+ 1 second to -/+ 10 seconds per day. The NH35 has a rated accuracy between -20 to +40 seconds per day under normal conditions.
