Just arrived - Squale 1521 50 Atmos Professional. It's certainly had a hard life and some bodging, but seems in perfect working order:
Feels like it sits high on my wrist, and at 13.1mm thick is actually thicker than Squale's claim of 12.5mm - given how it wears I'm glad I didn't go for the Marina Militare model at 17mm: now that would be quite the wrist-buncle! High it may be, but it's very comfortable, helped by the slim, tapering vintage-style FKM strap I've swapped it on to (the supplied OEM rubber being a bit clumsy and stiff).
What is good are the overall dimensions - it's a small 42mm (literally as well as how it wears, as it's actually 41.5mm in max diameter!). Legibility is superlative - for once you can tell someone who actually dived had a hand in its design, rather than the usual BS and hyperbole.
Time will tell if it's a keeper, I like it, and am pleased to be trying one at a sane price; the fact I'm not instantly infatuated is likely a good thing.
These are £1,075 now at full retail, which is enough for pause-for-thought. Quality is
acceptable, fit-and-finish seems decent, 316L steel everywhere, AR-treated sapphire crystal, beer-can aluminium bezel (my first in a LONG time!), basic Sellita movement, simple pad-printed dial with average lume... A lot of the cost is in the Swiss manufacture and historic heritage - there are
tons of micros offering equal or better specs for ~£500, but then there are also companies like Seiko offering some distinctly average watches around this price too. You pay for A Name.
