Choose the Baltic Aquascaphe Classic if you want a dive-style design, a rotating timing bezel and a higher manufacturer-stated water-resistance rating. Their listed steel versions share the same automatic movement and stated power reserve, so the decision is chiefly about design, dimensions and features.

Choose the Hermétique Tourer for a slimmer, field-watch profile
At 37mm in diameter, 46mm lug to lug and 10.8mm thick including its glass, the listed steel Tourer is the smaller and thinner option in this comparison. Its integrated crown gives the case a distinctive feature, while the absence of a listed timing bezel keeps the design focused on everyday and field-watch use. Baltic describes it as a field watch designed for exploration and everyday use: Baltic Hermétique Tourer Blue specifications.

The listed steel Aquascaphe Classic is 39mm in diameter, 47mm lug to lug and 13mm thick including its glass. Its 120-click unidirectional bezel provides a way to track elapsed time, which the Tourer’s listed specifications do not include. Baltic states a 200m / 20ATM water-resistance rating for this version, compared with 150m / 15ATM for the Tourer. Those are manufacturer-stated ratings, not by themselves evidence of independent dive certification or guidance to use either watch at a particular depth. See Baltic Aquascaphe Classic specifications.

Movement does not separate these listed steel models
Both cited versions use the Miyota 9039 automatic movement, with a stated 42-hour power reserve and stop seconds. Based on those listed specifications, neither has a movement or reserve advantage over the other.
Check the exact Aquascaphe variant before buying
Aquascaphe is a family, not one fixed specification. For example, Baltic’s Aquascaphe MK2 page lists 37mm or 39.5mm diameter options, 45mm or 47mm lug-to-lug lengths, 12.9mm thickness and 200m water resistance. It also lists a Miyota 9039 no-date option or a Miyota 9015 date option. These details differ from the cited Aquascaphe Classic, so confirm the model and size rather than applying Classic specifications to every Aquascaphe: Baltic Aquascaphe MK2 specifications.
