Seiko LM 5606-5070, Men's Automatic, 1977

The original integrated steel mesh bracelet is central to the character of this 1977 Seiko LM, reference 5606-5070. It continues the broad cushion-shaped case into one coherent wrist presentation. A rich blue dial, framed day-date window and automatic caliber 5606 complement the brushed and polished stainless steel exterior.

Original mesh bracelet and cushion-shaped case

The stainless steel mesh bracelet continues the case’s width, rather than interrupting it with a contrasting strap. Its integrated connection is part of this example’s original configuration. Together, bracelet and case emphasize a broad, relatively flat outline on the wrist.

The case measures 35 mm across and 41 mm from lug to lug, with a 20 mm attachment width. Softened square edges give the cushion form definition without making it sharply rectangular. These measurements describe a compact case whose overall presentation also includes the continuous steel bracelet.

Brushing across the broad upper surface contrasts with polished flanks and edges. The crown sits discreetly at the side, preserving the front-view balance. The caseback identifies the reference family and carries the watch’s water-resistance marking; it does not establish a current water-resistance guarantee.

Rich blue dial with framed day-date

The deep blue dial of this vintage Seiko watch contrasts with the brushed steel surround and mesh bracelet. Applied baton markers establish the hour positions, while narrow hands keep the center open. The cool color relationship between dial and exterior makes the brighter calendar frame particularly visible.

A framed day-date aperture at 3 o’clock supplies both weekday and date indications. Printed LM and automatic text identify the line and movement type without crowding the display. The blue surface, restrained markers and rectangular calendar window give the dial its clear visual structure.

Caliber 5606 and original components

Seiko caliber 5606 is an automatic mechanical movement powering the time, day and date display. The watch retains its original watch components and integrated mesh bracelet.

This used example is fully serviced and fully operational, and comes with a 12-month warranty.
