The community take
Owners talk.
Owners praise the Grand Seiko STGF387 for bringing the Shunbun dial to a smaller case, with one owner selecting it for its understated styling and quartz movement. Some owners find the diamonds unappealing, and others wish for a larger, diamond-free version for unisex appeal. There is a desire for a Spring Drive movement in a smaller case, though one owner chose quartz for its simplicity. The finishing and quality are considered by some to be on par with or exceeding Swiss luxury brands. Overall, owners rate the Grand Seiko STGF387 highly for its Shunbun dial in a smaller case, despite some reservations about the diamonds and movement options.
