Hello could you please explain what's the added value of the 24h face? I looked at some pics and feels too crumped; however I understand that it's preferred among pilots.

Thank you

Zulu time where I mostly fly is 8 hours off local time. If the watch is a regular 12 hour watch you have to do a mental calculation for time and as a pilot you learn that the less mental calculations the better, when a lot of things are happening in the cockpit.

It is true that the 24 hour display is cramped. But I got used to it after 15 years with this watch.

I cannot find the exact version that I have online, but this one is the closest:

I have mine on a nato strap.

What information are you receiving during flight that is in Zulu time? Are all communications done in Zulu time?

Yup. Weather, flight planning, most of the interaction with https://www.aviationweather.gov/

I think the watch you linked is the Glycine Airman GMT. I believe the standard hour hand actually has a 12-hour sweep (yes, even though the labels are both 24-hour) and only the GMT hand (pointing to the 10) has a 24-hour sweep.

From what you've described, you probably have the Glycine Airman Purist [1]. There is no GMT hand but the regular hour hand has a 24-hour sweep (and you can set the second hour dial).

(I also have a Purist.)

I was curious, so I dug out the watch. It is a Glycine Airman 2000. See here for a review from 1999:

EDIT: A couple of differences from the watch presented in the article:

- My watch has a transparent back.

- My watch is 42mm and not 40mm (I may be wrong on this last one).
