Seiko 5 Sports watches

Seiko 5 Sports is the line of automatic sports watches that Seiko relaunched in 2019 as a single dive-style design in 27 versions, sorted into five styles: Sports, Suits, Specialist, Street and Sense. All share one case, rotating bezel, hand set and dial layout, and a new logo with the 5 turned 45 degrees.

The Seiko 5 name goes back to 1963 and the Sportsmatic 5. The five stood for the traits Seiko built into the range: an automatic movement, day and date on the dial, water resistance, a recessed crown at 4 o'clock and a durable case and bracelet. The 2019 watches keep the recessed 4 o'clock crown and the day-date, use the self-winding calibre 4R36 running at 21,600 vibrations per hour, and are rated to 100 m. Watches by SJX called them diver-lite: they look like Seiko's SKX dive watches without being built to the same standard.

The styles differ in finish and strap rather than in the watch underneath, which is 13.4 mm thick with a Hardlex crystal and a 60-minute bezel. Sports Style models such as the SRPD55K1 (black), SRPD51K1 (blue), SRPD59K1 (orange) and the Pepsi SRPD53K1 carry sunray dials in SKX-like colours, on a bracelet or a NATO strap. Suits Style models such as the SRPD73K1 and SRPD71K1 come on Milanese mesh, a first for Seiko 5, or on rubber, with darker dials or a cream one and aged-looking lume. Street Style (SRPD77K1 to SRPD85K1) pairs a black hard-coated case with NATO straps and contrasting lume. Specialist Style keeps conventional colours: it includes a gold-plated steel case on a strap lined with crocodile-print calfskin, and the black hard-coated SRPD65K3 on rubber.

The SNZF15K1 uses a different case: 41.5 mm across and 13.2 mm thick, with a Pepsi bezel and a blue dial on a bracelet.
