Have a look at Helson watches
They do a SM300 style watch, they also do a BP50 fathoms homage, in my experience build quality is excellent as is the lume.
Our host will be releasing the Commander soon, (if you can get one in the 30 seconds a month the shop is open) his offerings are also fantastic.
Re the Steinhart, their quality is very good but the OVM is the only watch I knew I did not like the minute I opened the box, this was after looking at them on line for months. I placed up for sale less than 10 minutes after opening the package. For some reason in the metal it did not look as good as in photos and the straight lugs wore strangely on my wrist.
Re the Squale, my Mrs has an earlier version, she wears it every day, has smashed the living daylights out of it but it is still going strong, I would take a Squale over the Steinhart.
