What is the significance of 53?

[subtona]

New release... tell me, what am I missing?

[subtona]

And if it’s a new movement why is it too small for the case?

[ap1]

Some years have 53 weeks

[aeterna]

"Leap week"

[subtona]

Just read the press release, the press release, a year can begin mid-week, explained as follows.

A partially integrated weekly calendar
To display the day of the week and the number of the current week, Patek Philippe developed a totally new semi-integrated mechanism with a height of 1.52 mm, containing 92 additional parts. Thanks to a special plate developed and produced for this specific mechanism, the movement remains very svelte. A 7-point star on the hour wheel in the center of the movement controls the day-of-week display. Via a lever, a second 7-point star with an extended Sunday tip drives the 53-tooth week wheel. The calendar displays advance semi-instantaneously in discrete steps to avoid energy consumption peaks. Corrections of the day-of-week and week-number displays are performed with two push pieces recessed in the case flank at 8 and 10 o’clock. The date can be corrected with the crown pulled halfway out. Thanks to a fail-safe concept, the user can perform such corrections at any time of day or night without risking damage to the movement. The manufacture places great emphasis on convenience and user-friendliness. Pursuant to the international ISO 8601 standard, Patek Philippe chose Monday as the first day of the week rather than Sunday, which is commonplace in some countries. The first week of the year is the week that includes the 4th of January. The 53-graduation scale considers years with an extra week. This is the case every 5 to 6 years. The next occurrence falls in 2020.

That helps me better understand the gearing involved. In an earlier thread I had asked the same question about the 53d week # on the chapter ring.

Did some research and found that...

From financial world:
The weeks of the year in a Gregorian calendar are numbered from week 1 to week 52 or 53, depending on several varying factors. Most years have 52 weeks, but if the year starts on a Thursday or is a leap year that starts on a Wednesday, that particular year will have 53 numbered weeks.

From advertising world:
In 2017, the 4th quarter had 14 weeks with October and December each being 5 weeks long. The year began on Monday December 26, 2016 and ended on Sunday December 31, 2017. Additional years where there will be 53 weeks include 2023, 2028 and 2034.

"53" is the number on the infamous "HERBIE" volkswagen!

Unless it adjusts that week automatically, it’s pointless.

Why?
All mechanical watches need adjustment eventually. This one maybe once a year on some years. Other less complicated ones almost monthly.

Smartwatches are different but not mechanical.

Yes for the date - like a Datejust.

I was only talking of the new complication for week of the year.

If A new week begins on Sunday, once you reach the first Sunday of the year you should be on track for the remainder of the year?

TBH, I actually dont know, but that would make sense. As a side thought, I thought you were suppose to start the week on Monday with a 53 week system?

Prrsonally I use Sunday but Patek agrees with you,
“Pursuant to the international ISO 8601 standard, Patek Philippe chose Monday as the first day of the week rather than Sunday, which is commonplace in some countries.”

Further explained.
The year is not evenly divisible by 52 weeks.

365 / 52 = 7.0019

Leap year
366 / 52 = 7.038

Surely the sum should be 365/7 and 366/7
