I am a faithful of the brand, I own several and each time it is a great pleasure to have a watch Seiko wrist. My best part is u caliber 7D48 First perpetual motion, a beautiful mechanics. If I had to compare this SNXS77K I will say that we do not play in the same court and yet this little show, because it is actually a fairly small diameter, is far from ridiculous technical point of view . This class may be under this license Taiwanese rest of Seiko. It is reliable because it has been three weeks that I have the wrist and she did not take a second behind. When I was delivered and I had in my hands, I put together with lateral movement, gesture necessary for any auto show that it complies, for at least two minutes since then I have more shaken at all, being simply the wrist and the more I withdrew to sleep. The date is in dual choice, French or English as you will, not a perpetual motion, it is necessary to early (1 month on two actually) of each month 1 month. In short, a good watch, reliable, sturdy and attractive. I think people who have had problems with this watch have not had any luck, but normally Seiko has a customer service that works well.
