Diver watches

Two unrelated dive watch lines share the Diver name: Steinhart's Ocean and Triton divers, and the Formex DS 2100 Diver. Apart from the rotating bezel they have little in common.

Steinhart is a German brand known for Swiss-made watches, and its earlier models were largely homages to classic designs. The Ocean line runs from 42 to 44 mm in steel: Ocean One, Ocean Two, Ocean 44, GMT-Ocean 1 and Ocean One Vintage, plus a DLC-coated Ocean Black. The Ocean One Vintage Military (T0225) is modelled on the Rolex Military Submariner. The Ocean One Vintage Dual Time (T0227) is Steinhart's take on the Pan Am Rolex GMT and uses a Soprod A10 modified with a 24-hour indicator module. The Ocean One Titanium Premium 500 (P0921) swaps steel for titanium and is rated to 500 m, where other Ocean One models are rated to 300 m. The Triton is larger, at 45 mm, in steel as the Triton 100ATM and Triton 30ATM, and in bronze as the green-dial Triton Military Bronze and the Triton 30ATM Bronze Last Edition.

The Formex DS 2100 Diver has a 46.5 mm case in titanium and stainless steel, mounted on the patented case suspension system Formex fits to all its models, and is rated to 200 m. The Diver Automatic runs on the ETA 2824-2 automatic with date under a sapphire crystal; the Diver Quartz GMT has a quartz movement and a mineral crystal. Within each dial colour the references differ only in the strap, which the last block of the reference encodes: 2100.1.7020.100 is the black Automatic on the bracelet, .213 on calf and .910 on rubber.
