Very happy with the purchase.
It has been reliable and wears comfortably.
A little top-heavy but a very solid Construction
Watch feels heavy and solid.
Exactly what I like and very happy with the quality.
Thanks for the prompt delivery.
Quality and tolerances of the Retangula Emperor Tuna are second to none. Very clever case back with engraving. Be aware this IS a heavy watch, as it is made of steel rather than titanium like the Seiko’s 1000m tunas. Only (and minor) criticism is the 200m water resistance. This beast of a watch should have 500m at least.
Stunning watch, crazy value for the cost, and great communication, looking forward to future business!
