Seiko 5 6309-5500 Men’s Automatic Dress Vintage Watch

A wide gold-tone chapter ring surrounds the matte black dial of the Seiko 5 watch from 1979, reference 6309-5500. Gold-tone pencil hands and a framed day-date display sit within a brushed-and-polished tonneau case. Automatic caliber 6309 powers this 37 mm steel watch, which retains its original components and a multi-link Jubilee-style bracelet.

Black centre and broad gold-tone surround

The dial’s deep matte black centre contrasts with a wide gold-tone chapter ring carrying applied baton hour markers. This broad surround gives the display its two-colour layout.

SEIKO and the 5 logo appear at 12. AUTOMATIC is positioned above 6, with a shield emblem beneath it. A framed day-date aperture occupies the 3 o’clock position, keeping the calendar within the main face.

The hour and minute hands have gold-tone pencil shapes. A slim gold central seconds hand continues their colour, leaving the dial’s broad chapter ring visible around the indications.

Tonneau case and linked steel bracelet

The stainless steel head measures 37 mm across and 42 mm from lug to lug. Its tonneau outline combines a brushed top with polished flanks, while integrated lugs carry the case’s lines into the attachment.

A recessed crown at 4 keeps the control close to the case and provides time and date adjustment. The multi-link stainless steel Jubilee-style bracelet complements the tonneau form, giving this dress watch a continuous steel profile around the wrist.

Caliber 6309 and late-1970s character

This automatic watch uses the in-house Seiko caliber 6309 with day-date functionality. Automatic winding accompanies the calendar display within the main dial, keeping the watch’s practical indications together.

The broad gold-tone chapter ring and shaped steel case reflect the bolder dial and case treatments of late-1970s Seiko 5 design. Their contrast is the watch’s principal visual feature, with the slender hands keeping the central black area relatively open.

This example is in excellent used condition, retaining its original components. It is fully serviced and fully operational, includes a 12-month warranty, and is available for worldwide shipping.
