Variant guide

Partnered with the Nekton ocean research foundation; titanium construction reduces overall weight.

Buyer's guide

Titanium build appeals to buyers wanting a lighter daily-wear dive watch than the standard steel version.

Seller's guide

Titanium cases show wear differently than steel; note any brushing or surface marks honestly.
