Why does the GMT not have a lume-pip on the bezel like other models?

Seems a bit like cost-cutting to me, it would have as much use as a lume-pip on a dive bezel.

Exactly. The pip is for divers.

On a dive watch, the lume-pip performs a function when diving. The distinct pip at 12 is used to gauge how long you’ve been diving for, referenced against the minute hand. The bezel is also uni directional to prevent any accidental knocks when diving, messing up the gauge of time, meaning the diver is down longer than necessary.

On the GMT, the bezel rotates both watch to show a different time zones - so I presume the lume-pip would be a redundant feature. I don’t see why or how it would be a useful feature. I wouldn’t want it on mine.

If my GMT had a pip at the zero hour, for the life of me I would not be able to differentiate any offset without counting the clicks. I honestly do not think it would be useful.

It would be pointless.

Useless on a GMT bezel. A dive watch watch has a referenced start point to start a time. It is what it does. A GMT's bezel is not meant for timing, it is used to track the GMT hand and also calculate the time somewhere.
It would be pointless and look ugly in my opinion, another case where Rolex know what they're doing.

The pip indicates the zero time for a diver while timing time under. It's lumed to allow a diver to see elapsed time while in dark water. The 24 hour bezel is used to time different time zones and the pip is pointless for that purpose.

When you think about it, the 24hr hand doesn't really need lume either, since the bezel numbers are not lumed.

Rolex should lume the bezel markers. But they wont so tudor will in time.

With the exception of the original bakelite 6542 (which had radium bezel numbers) that's true for the GMT Master with a slaved 24 hand. In the dark with no bezel lume it was simply a 24-hour hand indicating which side the clock one was on like the later, first Explorer IIs.

However, with a GMT Master II's de-linked 24 hand one doesn't need to use bezel numbers to read the 2nd time zone. Once set for the 2nd time zone where midnight is indicated by zero-hundred, in darkness the hour is read the same as the regular hour hand except each lumed plot represents 2 hour intervals instead of 1.

That's fine in theory, but working out that if the 24 hand is between 9 and 10 then it's 7pm back home, or whatever, is kind of tiresome at 4am in a hotel room. I'd sooner just put the light on.

Because it’s superfluos, in a dive bezel it serves a specific purpose, time under water to calculate how much oxygen you have left in your tank.

GMT has a 24 hour bezel, no reason for a pip.
