What is a perpetual calendar watch? Watch and Learn #13

In today's episode of Watch and Learn, we dive into perpetual calendars. This neat little function keeps the date on track all year for you, so you don't to adjust the date from month to month. Additionally, it will keep track of the leap year, even adjusting for the inclusion of February 29th every four years.

We also briefly discuss why leap years are necessary, but also not quite as well known, that some years which should be leap years will not be.

Watch and learn is great series. Thank you so much for making these Marc. You are truly an asset to the Watch community.

So, you are saying that my perpetual calendar watch still needs to be reset by hand every 100 years? What is this garbage I'm spending my money on?! 🤣

This is a very interesting and helpful series, Mark.   I can't believe how much stuff you know. Thank you.

You’re awesome Marc! Thank you for the info. This watch is great. I would like to see you explaining the technical aspects of high end watches at least now and then. I know you’re very busy, but once in a while!

My seiko solar radio wave model XS055J with caliper 7B42 purchased from Japan actually have this functionality + solar + radio wave. Bought it since 2012 but didn't know it had this functionality but it is very well appreciated. It's quite a shame mine got black coating on the stainless steel so now it cannot be restored with brushing and polishing.

You are so oriented and know your stuff thanks for this great info

Didn't know about this model. I've got three of the Seiko 8Fxx perpetuals with 10-yr lithium batteries made between 2001 and 2003 from the date codes on the back. They were introduced by Seiko in 1999. Just replaced the battery in one of them that was made in 2001 - it's the third battery (counting the original). If you do it when it starts the double-tick warning and get the new one in within 3 minutes, it doesn't require reprogramming the year, month and date before closing it up. I've also got a perpetual kinetic auto-relay made in 2013. Provided you don't let it run down completely in long-term storage, it never needs reprogramming. The battery in this one that lasts five years - at best with zero chrono use and near zero calendar use - more like three years in practical use - defeats much of the perpetual calendar convenience other than end of short month - while imposing reprogramming year-month-date every few years. Kinetic is practical if worn almost daily to keep it charged, and solar would be much more practical.

I enjoy your educational and informative videos. This Seiko needs only to be reset every 100 years and most importantly every 2 years when changing battery. So, as much as watch is nice, it totally negates the advantage of owning perpetual calendar and not having to adjust it. Respectfully :)

Hi, is the writings on the dials luminated?

[boxingfan]

Mark, I bought this watch a couple of years ago. I've always had the day jump what appears to be 12 hours "early" and let it slide. I thought I had fixed a couple of days ago by going through the step again but it still does it. Can you tell me what I might be doing wrong or how you would bring the day increment 12 hours back. It certainly isn't as easy to set up as an automatic. Thank you for your great videos and much continued success!

[ProCelestialEmpire]

What a regret that they don't put this model with a solar powered movements...

Great video, love the watch, online it says there is a black dial, Arabic numerals version in 40mm, is that right the information online is ambiguous. Can't wait for the review!

Really enjoy this series. If you think it's relevant, why would one model of Casio (PAW/PRW 5000) not be able to be shipped to the U.S. per Amazon? I don't get it and have been trying to get one for some time.
