Having ripped apart the alpha to get fully functioning I was not impressed by the module build. Certainly not of the quality of the 70's Seikos. Attachment points for the zebras were spring steel and compression. In fact the alpha function, display and case quality are excellent, the module build, not so good but certainly adequate as you are never supposed to see it.
The roller function is nice but could be more robust with a real definite click between selected functions. No matter how I adjust the contacts internally to the stem, it des not always transition smoothly between sequential functions forcing me to hunt for the function I need.

P.s. gorgeous looking watch though, the v-alpa.

Some quality control issues have been a concern
They do score highly in design,exclusivity and display clarity,but in my experience there is another brand which equals them in sheer build quality, which is also exclusive, and highly desirable at a third of the cost.........
,i challenge anyone who has compared ,and handled both side by side and finds i am wrong.

(no hard feelings
(My eye sight is not as good as it was)Also if you remove the running seconds it leaves the display off set which i dont like.
but anyway the seiko was never really in the race for me - i think it looks out of proportion & the display doesnt look watch like to me - its trying too hard basically.
The whole solar powered thing comes into its own as soon as those battery changes loom.
