Seiko 5 7S26-3100 Men's Automatic Watch

A vivid orange seconds hand gives this 1999 Seiko 5, reference 7S26-3100, an immediate focal point. Its silver sunburst dial has dark-centered batons, luminous accents and a framed day-date window. The men’s automatic watch uses caliber 7S26 in a slim 35 mm steel case, paired with new dark brown genuine leather.

Orange seconds against a silver dial

The silver surface has a fine brushed or sunburst texture that catches light evenly. Applied baton indexes have dark centers, with small luminous plots near the outer minute track. The applied Seiko logo and 5 shield identify the line without filling the central area.

Straight baton-style hour and minute hands combine dark centers with luminous fill, matching the marker treatment. The bright orange central seconds hand supplies a contrasting color rather than another silver or dark element. That difference makes the running indication easy to pick out.

A framed day-date aperture at 3 o’clock sits at an angle within the dial layout. Its distinct orientation is another specific feature of this example, alongside the orange seconds hand.

Slim steel case and recessed side crown

The stainless steel case of this vintage Seiko watch measures 35 mm across and 41 mm from lug to lug. Tapered lugs and a polished bezel line give it a clean outline. The low side profile supports wear beneath a cuff, and the snap-on caseback continues the straightforward construction.

A small unsigned push-pull crown sits around 4 o’clock. Its ridged edge provides grip for time and calendar setting, while the recessed placement preserves the smooth case line.

The new genuine leather strap is dark brown with contrasting stitching. It fits the 19 mm lug opening and adds a warm color against the silver dial and steel case. The strap is a replacement accessory; the watch-head components are original.

Automatic 7S26 and prepared condition

Seiko caliber 7S26 is an automatic mechanical movement operating at 21,600 vibrations per hour, or 3 Hz. It powers hours, minutes, central seconds, day and date.
