US Divers SE3 supreme? What does supreme mean?

[Vq-1]

Came across a US Divers SE3 Supreme regulator the other day and cant figure out what the “Supreme” part of the regulator was!?! The SE3 looks like your standard SE3 regulator. Seems US Diver and Aqualung use the term “Supreme” a lot but what does it actually mean?

It might mean it is sealed

Sort of like their Artic series of regulators?

In current Aqualung items, Supreme indicates a cold water item.
I checked SE3 schematics, (same service guide as SEA4/Conshelf22/Aquarius/Pioneer) and I see no indication of any design difference for Supreme 2nd stages. So it was probably simply paired with the Supreme version of a 1st stage, which would have an environmental sealed dry kit added, perhaps even an oil filled kit for some items.

Does this have a 1st stage you can also provide a photo for? Looks the original was an SE2 first stage, and I can’t find a manual labelled for that model, so not sure what it looks like. Might be a Conshelf variant.

Here a pic of the first stage. It looks to be environmentally sealed.

That is the old oil filled conshelf supreme.

Awesome, thanks for all the info
