Chrono advice please

[petsco]

So I'm after another watch.

Choice of three at the moment. Slightly unsure which is best. It's all subjective, I appreciate.

Bremont Supermarine Chronograph in Black
Tudor Black Bay Chronograph in black
Brellum Pilot GMT LE3

I'm near Henley. So the Bremont appeals from that point. And can generally (always?) be picked up at a discount. Has the display caseback, and is a GMT. With the new releases today, Bremont appear to be changing direction; does this devalue the older ones (or make them more desirable?).

The Brellum has the display caseback, is a GMT, and is the cheapest, and most unusual. It is less waterproof, less Diver. Thanks to the delight of Brexit, slightly harder to get. Same movement as the Bremont.

The Tudor is the most common, sponsors Beckham (this is not a good thing...), isn't GMT, doesn't have a display caseback, but does have by far the best movement. The "poor man's rolex" doesn't bother me.

I do have a display caseback elsewhere, so that's less of an issue, but always nice.

Do I go on locale, rarity, or movement? I think it comes down to something that simple. Or are there anymore smaller brands I've overlooked.

Thanks!

To me the Brellum looks great. It would be ideal to see in the flesh, but as you say the reviews are generally favourable.

the only downside for the Breitling and Glashutte is the water resistance.

I may not be diving much anymore, but 30m just doesn't cut it for a daily wear. I'd be fearful of washing up in it (or having the ability to jump into a raging torrent to save a puppy. Or something)
