The Watch Appreciation Thread - Page 746

Dollar for dollar I don't think you can go wrong with a Speedy Pro.

If in house is important check NOMOS Glashutte, but if ETA doesnt bother you then check out some of the Mark ## watches from IWC, or even Tudor and Stowa

The pepsi bezel is most famous on the Rolex GMT. In that sense, there is no inherent purpose because the GMT function on that watch has nothing to do with the bezel.

Now if youre talking about the Rolex Submariner, the issue is not the color but the unidirectionality of the bezel that, as you say, serves as a time warning that oxygen is running low. "Unidirectional" is whats key here as it will never rotate the wrong way and tell you you have more time when in fact you don't.
 

Rolex cast a long shadow on subsequent dive watches (or watches in general especially in reference to the signature look of their bezels). The Seiko SKX401K for instance clearly fused the two. I don't think it has anything to do with a technically superior justification, just deference/homage/tactic to the style popularized by Rolex. Color, in general, would not be a good means to communicate such critical information because it gets dark in deep water. That's probably why  other companies introduced a vibrating alarm (JLC Polaris for instance which IMHO is THE dive watch to get).

Nowadays of course sensible people would most likely rock a sturdy quartz for such things...and on a slightly related note that Rolex Deepsea Challenge looks like a giant facepalm to me

As far as I know, no. It's for aesthetic reasons. The GMT Rolexes use a 50/50 split (for what reason I don't know--maybe world timer something?), and divers tend to use the last 20 minutes to highlight a warning threshold for  decompression/oxygen reasons.
