Seiko 5606-7100, Cal. 5606, Men’s Automatic Dress Watch
Separate day and date readings distinguish this 1970s watch, Seiko reference 5606-7100. Applied gold square markers with dark inserts sit over horizontally brushed silver, framed by a sculpted gold-plated tonneau case. Gold dauphine hands accompany automatic caliber 5606 inside the 35 mm head, fitted with a period-correct gold-tone folded-link bracelet.
Horizontal silver brushing and split day-date
The dial’s horizontal brushing gives the silver surface a linear sheen. Applied gold square hour markers contain dark inserts, with minute dots around the perimeter. The day appears at 9 and the date at 3 in a framed window, separating the calendar readings across the display.
The Seiko wordmark balances the dial furniture. Faceted gold dauphine hour and minute hands catch light over the brushed surface, joined by a slim central seconds hand. The lume and furniture show appropriate age, retained alongside the clearly defined marker shapes.
Sculpted plated tonneau and folded-link bracelet
The gold-plated tonneau case measures 35 mm in diameter and 38 mm from lug to lug, with an 18 mm fitting. Alternating polished and lightly brushed surfaces define its sculpted shoulders. A narrow bright bezel surrounds the dial, with sharp lines, tidy edges and a solid caseback completing the head.
The signed crown is recessed at 3. It operates positively for time and calendar setting, keeping the side profile clean.
A period-correct gold-tone folded-link bracelet accompanies the plating and has a comfortable drape. The dial, hands, case, bracelet and crown appear original.
Japan-built automatic 5606 and practical calendar correction
This automatic watch uses Seiko caliber 5606, a Japan-built movement in the 56-series. It supplies automatic winding, central seconds and a quick-set day-date mechanism. Quick setting adds convenient calendar correction to the unusual split display.
The horizontally brushed silver, square markers and sculpted gold-toned outline retain the restrained character of a 1970s dress watch. The modest diameter and short span are useful proportions to consider alongside its tonneau geometry.
This used watch is fully serviced and fully operational, running correctly with stable timekeeping. A 12-month warranty is included, and worldwide shipping is available with careful, trackable packing.
