NOS Seiko x Yamaha matching pair of quartz dress watches, produced as Yamaha promotional / corporate pieces.

This listing is for the pair: a 33mm men’s Seiko x Yamaha watch and a matching 23.5mm ladies model. Both are dual-signed on the dial with Seiko and Yamaha branding, giving them a great understated corporate/promo appeal without looking gimmicky.

The men’s watch is the main piece here: a clean 33mm gold-tone Seiko dress watch with a minimalist champagne dial, slim baton markers, matching gold-tone hands, and Yamaha branding printed across the lower dial. It has a very restrained Japanese dress-watch look — simple, thin, light, and easy to wear. The smaller matching watch makes this especially cool as a pair: ideal for a partner, collector, display set, or someone who likes unusual Seiko promotional pieces.

Both watches are new old stock and present beautifully. They are fitted to matching aftermarket brown leather straps with gold-tone buckles, which suit the warm champagne dials and gold-tone cases very well.

Condition:
New old stock condition overall. Both watches present extremely well, with clean dials, clear branding, and very attractive matching gold/champagne styling. As with most NOS vintage watches, there may be very minor storage or handling marks from age, but they have not seen normal daily wear. Water resistance has not been tested and should not be relied upon unless professionally checked.

A great set for anyone into vintage Seiko, JDM promotional watches, Yamaha memorabilia, minimalist gold dress watches, corporate-branded pieces, or matching his-and-hers / partner watches. The 33mm men’s watch is subtle and wearable on its own, while the matching smaller watch makes the pair much more unusual and collectible.
