Function:
The Seiko 5 SNXS77K has built the Caliber 7S26, with 21 jewels (Jewels).
In addition to the date it is the day of the week (three clock) and has a central second hand. The markers and hands are easily recognizable by luminous in the dark.
The crown must (not bolted, four clock) to set the clock be pulled in the first detent. So the date and day of the week can be set, first the date or day of the week from the day before. Then pull out the crown to the second position. So you can set the time, first you turn to 12 clock until the current date / day of the week appears, then presents you the correct time.
I wear the clock now already some time (two months) and the transition values are OK. According to the manual, the clock can in the month up to 15 (20) seconds have deviation (lead / lag). Exactly I have not yet checked or measured, but I set my clocks (of any type) once a week correctly. However, they may act only by a few seconds, because the time is correct to within a few seconds. The problem while setting the clock, the second hand continues despite the crown is pulled, so you can not judge by eg the hourly chime.
I had to cut the strap for my arm strength. One can at the clasp (with Seiko logo) the clock close filters (4 positions), which was not enough for me, I had to take out each bracelet page two limbs. This is not a problem even for the novice, if you proceed with care. The members of the clock are not a solid material, but strong enough, the tape does not rattle too much.
The clock has a bolted glass bottom, through which one can see the movement beautifully. The blue dial looks depending on the light from blue to black (or dark blue). The clock weighs about 90 grams.
Conclusion:
When my clock I found after a few days fluff under the glass on the dial. That can happen, but should not, especially with the Flusengröße!
In addition, the clock will stop relatively quickly, if it is not worn one day times (weekends). Therefore, I forgive four stars, where I have between three and four star wavered. Four Star (yet) because still is a beautiful automatic watch, which can look very sophisticated and is succeeded by design. Even the battery replacement is eliminated. In relevant forums we read of old Seiko that have run for years without Revison and start up again after a long time lying down immediately. It will certainly not be the last Seiko that I bought.
