Seiko 5 7009-3040 Chess Dial, 1987

A chess-pattern grid overlays the dark charcoal sunburst dial of this 1987 Seiko 5. Reference 7009-3040 pairs that changing geometric texture with luminous baton hands, a framed day-date display and an angular 37 mm steel case. The original signed Seiko bracelet, reference B16.03E, completes the watch’s all-original presentation.

Charcoal sunburst beneath a chess grid

The dial shifts between dark charcoal and black, with a visible grid across the sunburst base. The pattern changes in prominence according to the light angle, giving the face texture beyond its dark color. Applied baton markers and a clear peripheral minute scale sit around the grid.

The applied Seiko 5 shield is positioned at 12, with Automatic printing and a framed day-date aperture at 3. Broad baton hour and minute hands have luminous inserts, while a slim central seconds hand keeps the running indication light. The straight, faceted hands repeat the marker and grid geometry.

Brushed case planes and lower-right crown

Broad brushed surfaces and polished transitions define the tonneau-like, cushion-influenced steel outline of this Seiko vintage watch. A slim bezel line leaves the patterned dial prominent, while the slightly domed crystal softens the otherwise angular outline.

The case measures 37 mm across and 42 mm from lug to lug. Those dimensions provide both the width and overall length for judging wrist space. A compact ridged crown sits around 4 o’clock, reducing the interruption of the lower-right flank.

Original B16.03E bracelet and wrist fit

The original stainless steel bracelet carries a Seiko signature and reference B16.03E. Its brushed finish and close visual connection to the lugs continue the case geometry into the wrist attachment. The lug fitting is 19 mm, and the recorded wrist fit is 18 cm.

Automatic 7009 and preserved condition

Seiko caliber 7009 is an automatic mechanical movement operating at 21,600 vibrations per hour, or 3 Hz. It powers hours, minutes, central seconds, day and date.
