NH34 & NH35 Automatic – Setup & Care Guide

Hand-assembled in Los Angeles. Here's everything you need to know to get the most from your røwn watch. Select your movement below to jump to your guide.

Movement NH35

Getting Started

How to wind & start your watch

First-time setup

Your røwn watch arrives without a charge. Follow these steps to start it for the first time:

1
Unscrew the crown

Turn it counter-clockwise until it pops out to the winding position.

2
Wind 20–30 turns clockwise

This gives the movement enough energy to start running. Wind gently — stop when you feel light resistance.

3
Give it a gentle shake

This activates the rotor. The watch will continue to charge automatically as you wear it throughout the day.

Restarting after sitting unworn

If your watch stops after not being worn, simply repeat the winding steps above. The NH35 has a 41-hour power reserve — there's no need to overwind.


Setup

Setting the time & date

The NH35 features quick-set date and a stop-second (hacking) function for precise time-setting. There are three crown positions:

1
Crown pushed in — Normal operation

The watch runs normally. For screw-down crowns, always screw the crown back in after use.

2
First click — Set the date

Pull the crown to the first click. Turn clockwise to advance the date.

3
Second click — Set the time

Pull to the second click. The seconds hand stops for precision. Turn to set the time, then push the crown back in.

⚠ Important Never adjust the date between 8:00 PM and 4:00 AM. The date-change mechanism is active during this window and forcing it can cause damage.

Setup

Setting the time & date

The NH34 features a GMT hand in addition to standard time and date setting. There are four crown positions:

1
Crown pushed in — Normal operation

The watch runs normally. For screw-down crowns, always screw the crown back in after use.

2
First click — Set the GMT hand

Turn the crown to move the GMT (24-hour) hand independently. Use this to track a second time zone without affecting your local time.

3
Second click — Set the date

Turn clockwise to advance the date.

4
Third click — Set the time

The seconds hand stops for precision. Turn to set the local time, then push the crown back in.

⚠ Important Never adjust the date between 8:00 PM and 4:00 AM. The date-change mechanism is active during this window and forcing it can cause damage.
