Chopard

Sorry no picture to post yet, I just acquired an 1860/1 watch in yellow gold, white face.  It appears to be limited to 100 units.   It has 43 bees in the hinged caseback.  It is a gorgeous watch.   I have researched the threads on this site for the 1860, but is there anything else to add?   Are there other 1860 owners on this forum?   What are their ownership experiences?  Are there known issues with the hinge or caseback?   My caseback opens to 90 degrees and operates smoothly.  The movement seems to hack, but the hands jump when I push in the crown.  Is it supposed to hack?  Any suggestions for the hand jumping?   Is it bi-directional or should I only rotate the hands in one direction?  Also, as to hand-winding, how many turns should I expect to input from zero to fully wound?   Generally, what should I look out for as an owner of this watch?  Are there updates for the movement from Chopard?   It is not a screw down crown, so how careful do I have to be in relation to water?  Does anyone know general dates of manufacture for the 1860/1?    Thanks for all your help. 

Hi Robert

Thank you for the new purchase. 

I've not seen but read about this gorgeous piece.  This range or configuration has 100 pieces.

I will leave the rest of your questions to our friends who own this piece.

I'm surprised to hear that your watch hacks. 

For adjusting the minute-hand, you might want to try to adjust by exceeding the particular 'minute' by 5 to 10 minutes.  Slowly return the minute-hand back to the 'minute' you intend to set. Hold the watch firmly and depress the crown back.

I've asked before, to fully wound, will have to do at least 90 turns on the crown.  Well, need not be afraid of overwinding as it has overwinding protection mechanism designed in.

About movement update, not that I know of.  Just do NOT swim or bathe with the watch on.  While washing hand, if the water splashes, it should be ok, just dry it with a piece of cloth fast.

Got to leave the country, so quick answers:

NO: the 16/1860/1 does NOT hack seconds. if you have a stopping seconds hand, some "friction" is going on...you need to check it out.

YES: the minute hand does "jump" when pushing back the crown. This is minimised by applying slight back pressure to the crown whilst pushing it home. The pressure is enough to stiop the jump but not enough to change the set position.

CAREFUL with the hinge of the case back.....don't force it open too much.

LIKELY NO: the watch cannot be wound "fully" by hand, so 90 turns seems a lot because the automatic clutch kicks in at lower number of turns (? 40 turns depending on personal definition of "a turn") This protects the mainspring. I usually turn 30 "strokes" if the watch has stopped.

Greetings,

The watch you purchased is an earlier version of the classic 16/1860/2 or more commonly known as the LUC caliber 1.96. There is no mechanical difference between the hinged back version of 100 or the less limited general series 1.96.

 

Much has been written on this caliber including a fine disection by Walt Odet's.

 

Here is a photo of the watch, I have the standard 1.96.

Sorry, I hit the wrong button before loading the pictures. There was a yellow gold 1.96 with hinged back for sale for a long time on that famous auction site.

I noticed from the picture you posted some differences between that watch and mine.  When the gold case back is opened to show the see through caseback, on the perimeter of the gold case that encircles the see thru crystal, at top, the pictured watch seems to say 16/1860/1, is that correct?  Mine simply says 1860 in that spot.  At the bottom of the perimeter, the pictured watch has a 6 digit number (the case serial number) with all 6 digits conected.  My watch has 6 digits, but in two groups of 3 with a space in between them.    Does anyone know why these subtle differences occur? 

It is easier for everyone to understand your question. Thanks.

Sorry, my digital camera cannot take a clear picture and I do not have the necessary lens setup.   But the question is simple.   Did Chopard make the half hunter back 1860 in two forms, one marked on the case back with "1860" and one marked "16/1860/1"?  I ask this because my half hunter back 1860 is one of the first 25 ones made and is marked "1860", yet the one I see a picture of in this series of messages is marked "16/1860/1".   Can anyone help with this?

Hi Robert

Recently we have 8/100 for the 1860/1 and the pictures were in this thread:

chopard.watchprosite.com

However, the Part number is clearly engraved as  16/1860/1.





Chopard is not able to provide any information and also asked for a photo for verification.

Perhaps yours is an honest miss-out, and it is extremely unique then .

Chopard have confirmed to me, while they were in possession of my 1860, that they did indeed mark the very early yellow gold hunter-back as simply "1860", and later changed the marking to "16/1860/1" .   They will not say how many were marked 1860 but it appears limited to the first 25 or 30 of the yellow gold.   Mine is marked 1860.   Can other owners of the 1860 hunter-back confirm how their watches are marked?   The location of the marking is on the case back, with hunter back open, at the 12:00 location.
