Seiko LM 5606-7160 Men's Vintage Dress Watch

Emerald green sunburst and an English/Kanji day wheel give this 1971 Seiko LM its vivid Japanese-market character. Reference 5606-7160 combines automatic caliber 5606 with a polished cushion-shaped steel case. The original woven mesh bracelet is signed Seiko LM and carries reference XAM150, preserving the complete case-and-bracelet presentation.

Emerald dial and bilingual day-date

Strong radial brushing gives the green dial a shifting sunburst effect. Applied faceted silver-tone baton markers have dark central grooves, with an applied Seiko logo and Automatic printing above the center. LM 25 Jewels identifies the line below.

The framed, slanted day-date window at 3 o’clock has a bilingual English and Kanji day wheel. That language pairing is a specific Japanese Domestic Market detail of this watch. Silver-tone baton hour and minute hands echo the markers, while a slim central seconds hand completes the display.

Polished cushion case and engraved back

Smooth shoulders and flowing curves define the rounded cushion case of this vintage Seiko watch. Polished upper surfaces and a polished bezel frame the green dial, creating brighter reflections around its saturated color.

The steel case measures 36 mm across and 40 mm from lug to lug. A domed crystal adds subtle edge distortion at an angle. The overall span describes the case’s footprint beyond its central diameter, while the 18 mm lug width specifies the bracelet fitting.

A compact unsigned crown sits at 3 o’clock, close to the case, with a ridged coin-edge texture for grip. The solid engraved back carries reference 5606-7160 and lever-set instruction text. These visible markings remain part of the watch’s identity.

Original XAM150 mesh bracelet

The original stainless steel bracelet has a fine woven mesh construction. Its flexible texture sits beside the case’s smoother polished surfaces, keeping the emerald dial visually prominent. A Seiko LM signature and XAM150 reference identify the bracelet, and its recorded wrist fit is 20 cm.

25-jewel caliber 5606 and serviced condition

Seiko caliber 5606 is a 25-jewel automatic movement operating at 3 Hz. It powers hours, minutes, central seconds, day and date, including the bilingual day display described above.
