Blue dial watches have seen an increase in popularity in recent years, but the concept is far from new. While in decades past watchmakers have mostly produced watches with white, silver or black dials, a few blue-dialed timepieces managed to make their way out of the factory, but compared to their more austere counterparts, the color is still rare on the vintage market, aiding in their collectability and making them all the more desirable.
Grand Seiko 5646-7010

What we like: Clean, vintage Grand Seiko’s are relatively rare beasts as it is, but blue dial variants are next level. In fact, according to The Grand Seiko Guy, the 5646-7010 only came in white and blue dial variants, with the former outnumbering the latter 30 to 1. In addition to that, the watch has a stunning, sharp case design that was archetypal Grand Seiko back in the day, and an accurate movement ticking at 28,800 beats per hour. Also, the watch features a faceted crystal, though the seller notes that it doesn’t seem to match the watch reference number.
From the seller: This is an absolutely beautiful watch in stunning close-to-NOS condition. It comes complete with its original box, certificate, and GS buckle that is attached to a Seiko strap (we have no way to authenticate whether the strap itself is original). On a timegrapher in the dial-up position, the watch is running at around +/-0 seconds per day.
