Patek Philippe replica watches 5270 in Yellow Gold: The First Time Ever

The CH 29 is so awesome

1. Optimized tooth profile

This patent covers a completely new tooth profile for the central chronograph wheel as well as the drive wheel. These wheels have been unable to mesh properly in previous movements. This can cause chronograph backlash, or the seconds hand jumps backwards or forwards in an unattractive way. Patek Philippe replica watches has eliminated this problem with its new profile. This allows the teeth to slide into place, even when they touch point to point.

2. The column wheel allows for precise adjustment of the engagement depth

The second patent concerns the synchronization between the brake lever and the clutch lever. The brake must be turned off exactly when the clutch engages, and it must be switched back on once the wheel is released from the chronograph. These two levers used to be operated by the column wheel. They had to be manually adjusted and the timing correct, which was very labor-intensive and difficult.richard mille fake watches The arm of the clutch lever operates the brake lever in the CH29. Patek Philippe replica watches's watchmakers can adjust the timing and depth of engagement by using an eccentric screw attached to the clutch lever.

3. Optimized synchronization between the brake lever and clutch lever

The third patent was related to the eccentric cap for the column wheel. So, in order to comply with Geneva Seal requirements, the column wheel must have a cap. Patek Philippe replica watches engineers transformed this cap into an eccentric component that controls the depth at which the drive wheel, and chronograph wheels mesh. This is genius. It takes a previously decorative element and gives it an essential function. Bravo, Patek Philippe replica watches.

4. Slotted minute-counter camera

The fourth patent is related to the system that calculates the exact jumping minute. Lange Datograph was the first watch to use this type of chronocounter. This watch has a snail cam on its chronograph wheel, and a feeler which drops off the end the cam every time the second hand crosses the one-minute mark. The minute counter then moves forward.

This can cause friction and could be a drag on movement, especially when the torque from the mainspring decreases as it unwinds. Patek Philippe replica watches invented a system using a pierced camera with a gentle slope and an apparent spiral.Ulysse Nardin Replica Watches This is a sort of remontoire-d'egliate for the minute counter.

5. Self-setting hammers

Self-adjusting hammers are the fifth patent. The reset hammers that are used for the minute counter as well as the second wheel of the chronograph are all one piece on the Lemania 2310. It is difficult to get them to strike their respective hearts simultaneously. The CH 29 has a minute reset hammer that is individually spring and pivots on the second hammer. It is amazing that this has never been done before, but Patek Philippe replica watches managed it.

6. Between jewel bearings and hammers, a hammer pivots

Patent six is that the reset hammers are pivot between jewels to remove friction and add an ever greater aura of horological beauty to this incredible movement. The CH 29 oscillates at a much more stable 28,800 vibrations an hour, compared to the CH 27's 18,000 vibrations an hour.

History of the 5270

Now that we know how incredible the CH 29 watch is, let us look back at the history and development of the 5270. The watch was first launched in 2011. Immediately, you could notice several key differences.Patek Philippe replica watches The first was that the leap year indicator wasn't co-axial with the minute counter (as in 3970/5970), but instead took the form of two apertures.
