my new Longines with GMT complication has the usual caveat of do not adjust the quickset hour hand between 8 and 2, why is that? its a real odd one coming from a non watch guy background.

I actually will use it as a GMT and landing after 8 which I often do is a problem, is there a work around?

What happens when you set date between 10 and 2?

If the time of your watch is somewhere between 10 o'clock and 2 o'clock and you start changing using the crown, the quickset gear will not engage correctly, and attempting to change the date may cause damage to the watch's movement. This is because the quickset mechanism is designed to engage with the date wheel at a specific point in the watch's movement, and attempting to change the date outside of this range can cause the mechanism to jam or break.

Watch with a midnight stop

In addition, some watches with a date function have a feature called a "midnight stop," which prevents the date from changing manually during the hours around midnight. This feature is also designed to protect the mechanism and ensure that the date changes smoothly and accurately.

So, in summary, you cannot set the date of a watch between 10 o'clock and 2 o'clock because the quickset mechanism is designed to engage with the date wheel at a specific point in the watch's movement, and attempting to change the date outside of this range can cause damage to the watch's mechanism. It is always best to follow the manufacturer's instructions and set the date during the recommended time range to avoid any potential damage to the watch.

thank you storm, that helps a lot with my understanding of these types of watches. Although the issue I face is to do with the quickset hour hand ajustment.
