The DS: Jerome‘s double split, Suitbert‘s double rattrapante and my double chrono

As you can see in the headline: the DS is quite a divers chrono.
The original discussion started actually in the Patek forum as Jerome was introducing, in an inpressive post once more, the new 5204 p.


From my point of view it is a double chrono as you can measure time intervals that are not linked to each other.
This is in contradiction to Jerome‘s view: "The two measures are necessarily linked".


In contradiction to Suitbert: "This is more comfortable with the double split as you can take more time to record the split time, minutes are split as well".
You do not have to take your time / care to record the split time as you can freeze / keep the rattrapante record as it
is on the dial.


And here it comes in detail: you start the DS by pushing the button at two o‘clock ... both hands start to run.

Than you push the button at ten o'clock at the moment the event / race / incident is finished ... the rattrapante hands second and minute do stop.

AND NOW the trick: you use, with the chrono hand still running and the rattrapante stoped, the FLYBACK button at four o‘clock, when

you want to start to record a new time / a new attempt to beat this rattrapante time which is your reference time now.

THe result is that that the chrono hand flies back and starts another measurement and if the reference time is beaten you press TWICE

the pusher at ten and what will happen? The stationary rattrapante hand will catch up with the chrono and stop immediately again.

Hence: you do not have to record a beating time!

And what is EVEN more impressive: the above scenario was for a longer new time ( " ... the rattrapante will catch up ..."), but the rattrapante

hands ( both!: second an minute hand) will JUMP backwards if the new time is shorter.


And you can take as many comparing measurements as you like in a VERY comfortable way as you have 30 minutes time left to prepare

for the new race / event as the chrono is still running for a comfortably long time left.


As Suitbert was asking: "Is it worth the plus in complexity?"  The clear anwer is: YES.

You have got two 30 chronos in one watch and on top the luxury to have 30 minutes to spare until the next time record.

Also financially: in comparison to the 5204 you can get a DS and a Datograph Perpet. both in platinum and you still have got money to burn ... for a mid range Patek, for instance !
