This watch is able to change the date indication instantly between 0:00 a.m. and 0:05 a.m. In case of conventional quartz watches, the date indication changes gradually between 9:00 p.m.

and 0:00 a.m. You should understand that if you want a quatrz watch with on-the-spot date change you have to get one with "smart" quartz technology, which has a separate time keeping "computer" and set of electric motors moving the hands and the date wheel. Something like Longines V.H.P.

Do not set the date between 9:00 p.m. and 1:00 a.m. Amending the date during this time period may cause problems such as the date failing to change the next day.

Hi, Don't know if there's an easy fix, I have purchased a Seiko Grand Quartz 9943-8010. I can alter the date and day using the crown, but it wont change each day if I don't change it manually. thanks.

INSTRUCTIONS FOR ANALOGUE QUARTZ AND MECHANICAL WATCHES Your watch is one of the following six types of analogue quartz and mechanical watches. Before using your new watch, please read the instructions pertaining to your watch type; they will help you to get the best out of the watch. "This watch is able to change the date indication instantly between 0:00 a.m.

and 0:05 a.m. In case of conventional quartz watches, the date indication chang. Interestingly, Seiko (at least) uses plastic for the hour/minute interface to the date wheel because it's more likely to absorb the force if some one accidentally changes during that time, and it becomes the week point to ensure more is not damaged.

It's incredibly simple to replace as well. Grand Seiko SBGX059 window date does not change at exactly 00:00 😱Powered by a 9F62 quartz movement. One of the most accurate quartz movement on the market.

The watch is provided with a date and day of the week function and is so designed that the date and day of the week change once every 24 hours. The date changes around midnight, and the day of the week changes at around 2:00 a.m. If AM/PM is not properly set, the date will change at 12 o'clock noon, and the day of the week will change at around 2:00 p.m.
