Durrant GMT - User Guide

STIRLING TIMEPIECES OPERATION GUIDE

The Stirling Timepieces Durrant GMT incorporates the NH34 automatic movement. Those familiar with the NH34 movement will recognise it for its durability and robust nature, it was picked with the user in mind.

OPERATING THE CROWN

In order to free the crown it first needs to be unscrewed anti clockwise until the crown pops open. Once the crown has popped it can then be rotated clockwise to wind the watch.

The NH34 movement used within the watch is an automatic movement. Constant use of the watch will ensure the watch continues to run. A fully wound watch can rely on its approx. 41 hour power reserve to keep it moving before it stops.

Incorrectly securing the crown is one of the most common user faults when operating a dive watch, so it’s crucial you ensure it is seated correctly. To secure the crown, apply pressure straight towards the watch case and screw the crown clockwise until it is completely flat against the case. Always ensure that the crown is secured to avoid possible exposure to dust and moisture. If the crown is not secured correctly, water will enter the dial and damage the internals.

HOW DO I CHANGE THE TIME/DATE?

Unscrew the crown anti-clockwise until you feel it pop. Gently pull the crown out one click and rotate counter-clockwise to change the date. In the same position, rotate the crown clockwise to set the GMT hand.

To set the time, pull the crown out one further click and you will notice that the second hand will stop. From here, move the hands clockwise to set the time.

Do not adjust the date between 9PM and 3AM. In the NH35 movement the gears are engaged during this time and movement of the gears can cause misalignment which could inflict damage on the gears.

Some final take away points:

We want to help: If you have any problems with your Stirling watch and are unsure if you are covered, get in touch with a member of the team. We are here to help and will always work with you to offer a solution to the problem.

Watches aren't 100% waterproof. All watches are in fact water resistant in line with their guidance and thresholds as per manufacturing. All Stirling Timepieces are factory tested up to 200m (20atm) and are more than capable of dealing with such experiences. Although we can guarantee that, we DO NOT recommend you wear your Stirling Timepiece in any location that will expose the watch to unnecessary heat or hot water. This includes the shower, bath, steam room or a hot tub. Such conditions may cause the seals to swell and allow water to enter its internals. Although this is uncommon in our watches, we always recommend against taking the risk. A prolonged exposure to heat or steam can sometimes leave a build up of moisture underneath the sapphire face which will cause problems to the mechanism. 

Avoid a watch winder. A watch winder will keep your watch running, but in reality it will expose your watch to continuous wear and tear on the movement. Your watch has a 41 hour power reserve, take if off for a day and it will still be ticking.
