Grand Seiko has expanded its Heritage collection with deep blue and white dialed three-handers in its Grammar of Design style.
Both steel watches, which use the 44GS 36.5mm case design, have strongly textured dials with grooves radiating out from the centre and presented under box-shaped crystal.
They are powered by in-house mechanical 9S64 movements with 72 hour power reserve and accuracy of +5 to -3 seconds per day.
They are water resistant to 100 meters and go on sale in November and can be pre-ordered for £4,900.
