Day Date Clock

[peetee]

An example of frustrating, ill-thought out technology Mick. And I have another one for you. Our kitchen clock is battery powered and checks it’s time against an internet signal. If the battery fails when you replace it the clock adjusts itself by spinning the hands round at great speed. This is a bit of a drain on a single AA battery but what makes it far worse is that the clock ‘brain’ doesn’t understand that visually 07:00 hours is the same as 19:00 hours. If, for example, I notice one morning at that the clock stopped at 07:30, when I replace the battery the hands fly round over two full revolutions when one and a bit would do. So in a matter of minutes your battery has been drained of a large proportion of its power! I have had the clock about 14 months now and it’s on its fifth battery.

Here we are, 2021, phew!
But my clock query is simple = "Can a water clock really keep good time during a drought"? MM

Sir, Sir!

I have a mechanical watch with day, date, month and moon phase.

It sits in a watch winder when not being worn as it’s a pain to reset it all.

Watch winder - is it human? never knew such things existed, can you post a picture.

Brilliant!

Haven't you asked this question before?

D'ya know?
I think you're right.
I have a habit of repeating myself.

It’s basically a box in which the watch is strapped to a padded cushion. The cushion is then rotated to keep the watch wound. Note they only work on automatic movements.

Movements can be wound either clockwise, anti-clockwise or bi-directional and different movements required a different number of rotations per 24 hour period. These can be adjusted in more expensive models of winders.

An example of one below without a watch in place.

Do such things exist for a manual winder?

[Syd]

The only one I can find available is the Orbita Sempre which costs $3,000 for a single and $5,000 for a double winder. Not exactly cheap though a pre-owned one is available on Chrono24 for £528 plus shipping from Russia.

The clock we have on the wall in the kitchen (battery driven) has a day and a date window.
The day and date change over at midnight of course, but it's not an automatic system.
This means that when there isn't a 31day month, the date is wrong the following day. The day of the week is always correct of course, so we have to move the date on manually.

Question:
Today, the clock is correct. Friday 1st.
On Monday Feb 1st it'll be correct too, as January has 31days in it.
By the time we get to Monday 1st March, the date will be shown as 29th. April, June and September will exacerbate this issue.

So .......... if we never corrected the date, when will the clock's date be correct again?

Yep and in under a month. You just need to remove the battery.
