Review – Seiko Prospex GMT Kinetic Tuna Air Diver 200m aka SUN021

Reference to the SUN019 review here :

https://seikoparts.wordpress.com/2014/07/29/review-seiko-prospex-gmt-kinetic-tuna-air-diver-200m-aka-sun019/

I have the opportunity to purchase a SUN021 and since i like the SUN019 (bracelet model), i jump into buying it.

Basically they are the same watch but with the following difference :

-black PVD bezel painted in yellow colour,
-Blue GMT hands,
-yellow minutes hands,
-Black PVD crowns (both crown),
-rubber strap.

Some picture below :

This is a new type of Seiko rubber strap. It is softer, its 24mm width and scale down to 19mm at the buckle (Yes ! 19mm !)
The buckle is signed “Seiko” and there is only one keeper. The keeper is also signed “Seiko” and its made of stainless steel. It is pretty comfortable ; as compare to the traditional Seiko rubber strap which are usually very hard.

One issue i noticed about this rubber strap is that it may be too long for Asian people. I usually wear my watch “loose”, which may measure to about 7″. But despite that its still a little long with its tongue-end sticking out a little.

As usual the wrist shot.

*although they are the same watch, somehow the SUN021 wears smaller than the SUN019…….. it could be the bracelet on the SUN019, which has a slight curve at the lug. It may also be the black PVD bezel on the SUN021 which makes the watch less pronounce. Mmmmm……………………

I am having it charge now with the Braun Toothbrush charger. It should give me full charge in the next 2 days.
