Seiko 5606-7100 - horizontally brushed silver Dial
The dial presents a horizontal brush across a silver field, producing a refined linear sheen. Applied gold square markers with dark inserts provide excellent contrast and depth. The unusual split calendar—day at 9 o’clock and date at 3 with a framed window—adds character without clutter. Minute dots track the perimeter for precise reading, while the Seiko wordmark balances the composition. Overall legibility is excellent.
5606-7100 - Hands
Elegant gold dauphine-style hour and minute hands pair with a slim central seconds. The facets catch light attractively over the brushed ground, maintaining a classic dress-watch look and assuring quick time reading at a glance.
Seiko 5606-7100 - sculpted tonneau Gold-Plated Case
The tonneau case is gold plated with alternating polished and lightly brushed surfaces, emphasizing its sculpted shoulders and narrow bezel. The geometry wears flatteringly on the wrist and frames the dial with a thin, bright rim. Case finishing is consistent with period Seiko quality—sharp lines, tidy edges, and a solid caseback.
5606-7100 - Crown
The signed crown sits at 3 o’clock, neatly recessed to keep the silhouette clean and comfortable. Operation is positive and secure for setting time and calendar.
Seiko 5606-7100 Bracelet
Fitted is a period-correct gold-tone folded-link bracelet that complements the case. It delivers the authentic vintage look and comfortable drape one expects from a Seiko dress piece of this era.
Seiko 5606-7100 — Movement: automatic caliber 5606

Heritage of the Seiko 5606-7100 in the dress-watch era

This historic wristwatch stands as a collectible expression of Japanese horology heritage—an era when Seiko set benchmarks for precision and reliability across accessible price brackets. For collectors building a representative Seiko lineup, a 56-series automatic dress reference is a cornerstone.
