Master Eight Day Perpetual Problem

May 20, 2023,23:46 PM

Hi all,

I haven’t worn this watch in over three years. Today I pushed the adjuster around 1,200 times to set it to the current year and date and the calendar now reads Saturday, May 21, 2023. It is Saturday, May 20, 2023! Why is it one day off and what if anything can I do to correct the erroneous date? 

Thanks in advance.

Second time today we have heard the same story the other was an IWC.

Start to wonder about resetting today. It seems only the manufacture can adjust it. Ps: was it a one pusher adjustment.

“Easy” way is to pull the day of the week hand and move it over one

The “right” way is to send it in and some watchmaker will do it for you. Some cog jumped an extra space during your excitement. Not uncommon, sadly … Cazalea

Thanks. Ironically, in 2018, I screwed it up by setting the perpetual calendar in the forbidden hours. I paid $1800 to have it serviced by the factory. I’ve probably worn it five times since then and it looks like I’ll be paying $1800 again very soon! ...

Now you tell me ;-)

JLC should really engineer away the forbidden hours.

Other companies have. JLC surely can but have chosen not to. A shame.

Pffff, a pity.

Who would you recommend I contact at JLC to ask? Maybe someone will sympathize with me since I already had the PC serviced once and this time, I set it correctly and this shouldn’t have happened. Thanks for your suggestions. BTW, I’ll be in Paris this wee... 

RD, did JLC set it correctly in the first place?

Always a possibility. I didn’t check the date correctness while I was busy pushing the adjuster 1,200 times to bring it to the current date. Arduous process. My right fingers, hand and wrist are still sore from the exercise! I love the ease of adjustment ...
