NOTICE: Please read these instructions in whole. They will give you a good understanding of the operation of your movement, and reduce any potential damage to the Cal. NH35 operation.

Warning: Do not operate the date quick set from the crown between the hours of 9pm and 3am as you risk rendering the date change mechanism useless. If you don’t know the time, don’t change the date. More on this to follow.

Manual Operation of the movement is controlled from the crown, some may call this a winder. The crown has three operating positions that control the different functions and complications of the Cal. NH35 (movement). Selecting the desired operating position is achieved by pulling the crown out gently. If you pull it too far, aiming to achieve the second position (date operation) you can simply push it back in and gently pull again.

Hand-winding – Calibre NH35 (movement)

The first operating position of the Cal. NH35 (movement) allows the user to hand-wind the watch.

The first position is where your crown is at rest. This can vary depending on your watch’s case design, but there are two options.

  1. You have a sports watch where the crown screws closed to create the water tight seal.
    The first positions is found by un
    screwing the crown until it is no longer engaged with the locking mechanism on the case.
  2. If your watch does not feature the screwed crown. The closed position (most pushed in) is the first operational position.

The first operational position is where you can hand-wind your watch. Essentially, this is putting power into the reserve. Approximately forty hand-winds of the crown in a clockwise rotation in this position will supply the reserve with a full supply. This will last approximately forty-one hours if unworn. If you intend to wear your watch every day, your watch will require no further winding as your movement will supply power through the autowinding mechanism.

Date Quickset – Calibre NH35 (movement)

The second operating position of the crown controls the only complication on the Cal. NH35 which is the date quickset.

Warning: Do not operate the date quick set from the crown between the hours of 9pm and 3am as you risk rendering the date mechanism useless. If you are unsure of the time your watch is displaying with regards to the 24-hour date function, skip to next, the third operational position, and follow instructions to change the time so you are sure to be outside this region of operation where your risk damage to your timepiece.

Changing the date is done by turning the crown anti-clockwise. You will see the date wheel complete a part rotation and the next number will drop into view.

Setting the Time and Hacking – Calibre NH35 (movement)

The third operating position of the Cal. NH35 (movement) controls the setting of the time and hacking (stopping) of the second hand.

The third and final operating position can be reached by pulling the crown out to the final position. You will notice when the crown is in this position, as the second hand will stop moving. This is the hacking feature of the Seiko Cal. NH35. The crown rotated in a clockwise position will move the hour and minute hands in a clockwise rotation. You should set the time by using the clockwise rotation for the bulk of the movement. It is understandable that you may miss the time that you wish to set your watch to. In this case, micro adjustments to the time in an anti-clockwise rotation are fine, but if you move over a few hours past, it is recommended that you continue the clockwise rotation until you achieve a full rotation.

DON’T: Turn your crown anti-clockwise in the hope that the date will go backwards. It will not. You will not be happy with the results!
