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.
To see watches and clocks with perpetual calendars, check out the selection on our website at: longislandwatc...

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

[@islandwatch]

Gracias!

Hey Rob you are everywhere lol 😹

[@Davitamon76]

Love this series. Cup of coffee, sit back and just watch and learn.....There's is always something I didn't know before or wants me to read about/research further. Great episode! Also, looking forward to the review on the SPC131P1. Thanks!

[@islandwatch]

It's already shot! Will come out next week. Get the coffee maker ready!

[@JunkfoodZombieGuns]

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?! 🤣

[@TheRealMafoo]

If that's something you just can't live with, try a radio or GPS controlled model. I would go GPS, as I doubt the radio signal will still be broadcasting in 81 years :)

[@alexlo7708]

@@TheRealMafoo I don't think so. Yr GPS model'd go void because it might fail to function as old window can't be updated.

Nope. Only three times every 400 years. You didn't have to worry about it in 2000 and needn't worry about it in 2400. Hope that helps reduce your anxiety level.

Excellent video! Love the look of that Seiko. I have a Citizen Eco-drive perpetual calendar & chronograph watch. I never had to set the date again so far after its initial setting up.

[@islandwatch]

I do like it!

I just wanted to say thank you for making the videos and I love the Seiko in the video too. I think I found my next watch purchase. Ive always wanted a nice seiko chrono anyway. lol

[@islandwatch]

Great to hear, thank you!

[@jaimerivera2545]

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!

Seiko SNP039P1 premier kinetic perpetual calendar with leap year correct. Fantastic, as are the other similar models, yes I know its not mechanical, but its a fantastic watch I have had for sometime. Fantastic reviews and information Marc, like your easygoing no nonsense approach. Brilliant.

[@benwong1111]

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.

[@memonion4515]

Just bought this watch after watching this video Amazing piece!

[@sunnyr8434]

This is a great series. Thanks!

[@Sparks68]

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.

[@jameelshehadeh9011]

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

[@BruceButterfield]

Thanks Mark... Very informative

[@islandwatch]

Thanks for watching!

[@stevesibaja3123]

Some analog watches they do feature Perpetual Calendar other watches you have to set it manually depends on the watch brands

[@lohikarhu734]

Adjusting the Citizen E510/E710 perpetual calendar is kind of "fun" ;-) I always have to refer to the booklet (itself, hard to find) if I have let the watch run down (very, very seldom, but twice in 12 years)

[@mkphilly]

Love my seiko.... really surprises how complicated it is for the price

[@MTCKIE68]

So Very Cool !!!! I'm learning so much from You and these videos !!

[@sans3698]

The only thing that bugs me is that they could've made the date indicator hand a little bit more longer. Just a personal preference but love the watch otherwise. Oh and they could've avoided the tachymeter haha Thanks for the info as well.

[@teamhonn]

thanks mark for the great info.

[@BobbieGWhiz]

I'm not a "Watch-ie", but I'm interested in the calendar, and you know your stuff. Thanks. Too bad that the 400 year leap year rule came in to effect in the year 2000 (that overrode the 100 year non leap year rule) so the general public wasn't given the opportunity to learn that we don't always have leap years every 4 years.

[@islandwatch]

Very true!

[@STohme]

Nice video Mark, thanks.

[@raymondmalone9721]

Yet again another great W&L. What a nice looking seiko 😍

[@islandwatch]

Yes, wait till you see the other versions

[@jorgemtds]

Great explanation Mark. And very nice watch.

[@islandwatch]

Appreciate it.

[@frenchaccent540]

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 :)

[@ChintanPandya01]

Awesome series! Keep em coming! We are there with you.

[@CAfakmykak]

Hey Mark are there any Perpetual Calendar complication's for under 10,000 USD? I really wanted a Grand Seiko but noticed that they do not have any. All of the other's that I have seen used online seem to be 20,000+

[@stevenstocking5855]

Very interesting Mark. Can't believe I sit watching vlogs on watches but hey....

[@islandwatch]

Nothing wrong with that. . .

[@MAZiese]

Mark I always enjoy watching your in-depth reviews of watches and how to set them up. My question is when fall arrives what is the procedure for rolling back the time one hour on the 7T86 movement for this watch? Is it safe to turn the crown counter-clockwise or will it damage the movement?

[@Sparks68]

Doesn't matter. When you set the time by pulling the crown out to the 2nd position, it cancels all alarm settings. After setting the time on the main dial using the crown, you use the pushers to set the alarm subdial to the same time. At the time sync you push the crown back in. The date changes when the subdial time at the six hits midnight (i.e. 24/0 hours), not the main dial and it doesn't affect the date in time setting mode. Even when the alarm is set, the internal IC knows the current time on the 24 hour subdial and it will still change the date when it hits midnight. You're thinking all the day, date, month and year are mechanically driven by a wheel train off the main hour hand. They're not. It's all electronic with the IC kicking stepper or ultrasonic motors.

[@KakashiHatake-ou7mp]

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!

[@makerofmanythings8447]

Man this watch solar powered would be phenomenal, but I'm still buying it like it is. If or when it comes out in a solar version I will have another one. I currently have the citizens perpetual calendar but it is less convenient to operate functions, this seiko is much easier. Love the classic looks of the seiko perpetual calendar. 👍😎👍

[@boxingfan5742]

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!

[@dushancg8817]

Set it 12h back

[@flip7081]

Great information. I'm looking for a "nice" one" with these, but they always to be expensive, out of my price range and / or don't have one with all the features that I want (actual numbers, NOT indices, hand applied or not, and that it's not look to dressy!I just don't dig them, AND yes about half way through, I gave the vid a thumb's, and hit the subscribe button!.This one sounds awesome. I've been looking at the Seiko site for a while, and do not remember seeing this. I've been considering a Citizen because, as you noted, the recharge capacity it has, but that's hit or miss. For a little while I've also been considering a Longines Master Collection L2.755.4.78.6 but damn their expensive) Day and date, that really all I care about. With it (Seiko) being a quartz drive, I'd assume that they're fairly resilient? I am admittedly rough on a watch, less so now as recently I've since changed jobs, but still, I'd say fairly a bit rough. Thanks for any help you can give!

[@VictorC1891]

But the Orient SPORTY AUTOMATIC EU00002D and EU07008D are Multi-Year Calendar watches, and they are pretty affordable as well.

[@WuBloodKin09]

Good video Mark, very informative...had a question, are master calendar watches the same as the perpetual calendar watches?

[@islandwatch]

No. The Master Calendar is a JLC term, and just refers to the display of calendar variables. It does not adjust for months less than 31 days.

[@Iberian247]

It would be interesting to find a watch that would also compensate for Daylight Savings Time.
