Yes I just recently learnt about the existence of and became obsessed with saturation divers. Such a bleak life, like being in the special forces, disappearing for secret tours then spending your off-time staring into the middle distance.

Are you ok at the end of your career? Assuming you avoid any work related injury / catastrophe and retire happily at a time of your choosing, is your body ok?

At the risk of being morbid, have you read about the Byford Dolphin accident? Proceed with caution, but learning about that only made me more in awe of those guys, the lifestyle and the equipment.
There is also a documentary which I've been meaning to watch called Last Breath, which sounds fascinating. https://www.bbc.co.uk/news/uk-scotland-north-east-orkney-shetland-47826802

I've done 30m which with a few of mine. 40m is usually the maximum for recreational diving before you get into technical diving. I know people who have gone down to 75-100m but really unless you are wreck diving there's no that much to see at those depths as all of the "pretty" marine life is 40m and above.
There are people that do deeper dives for oil rig / pipeline work and maintenance but that is hugely specialist and hugely dangerous, but very, very well paid.
Everyone uses digital dive computers now anyway so the point is moot. I only use my dive watches as a back up to my computer.
tl;dr - depth markings over 100m are usually a statement of quality rather than useful user guidance.
