How many of you 7750 owners use your chrono function?

Exactly. Chronos are not to be played with unless you want to spend more money fixing them, or happen to know how to fix things yourself!

Um, Wat, you're being a bit too paranoid, the problem he has is of a loose chrono hand, not a problem with the movement, it's a cheap fix. I think you're trying to say, reps are what they are, reps. ;)

Never Never Land
Never and I have had many a 7750.

Obsessed with chrono look but never used the function.

It all started with a breitling navitimer then it became a Rolex Daytona now it's a AP ROO.

When will it end ?

What about the chronos on the 7750s that get converted to manual wind for vintage Daytonas, like the spinmaster ones?

lol, as if it doesn't happen with the gens. Here's a $40,000 Patek, notice something funny? ;)

So far so good after more than 1 year and constant chrono use (this one is from DW not Spinmaster, movement has not been serviced either):

Removing the rotor and the extra parts of the winding mechanism won't help the chronograph module's durability though. There's still a bitter taste in some people's mouth's when back in the day the older A7750 models were very problematic, the new ones barely have issues and most of these issues are due to them being improperly oiled/bone dry, they're not perfect by any means but they're not bad either, a proper service will not only revive a dead A7750 movement but it will also make it extremely reliable, I could even go as far as saying it will be as reliable as its ETA counterpart once properly serviced and oiled.

These arguments pop up from time to time, and they're generally a good indicator of who is familiar with gens, and who isn't... Gens aren't perfect just cos they're gen, they're just gen. They still break, still have issues, still don't like to have the date wound forward between 11 and 1, and still need maintenance.

Personally, i've never had an issue with any of my chronos, gen or rep, but i know plenty that have. Then again, after seeing people stop the chrono at 6 o'clock and reset it from that position regularly and hack the movement and start winding without proper care that the desired position is engaged, i'm not surprised that some have endless issues with their watches. I look after all of my watches as if they're worth thousands and thousands of dollars. If they need repair, they get it.

I agree with guanaco.

Could you please explain further on the hacking the movement? I hack the movement on the watches that I don't wear, and someone told me that should be done to minimize wear.
Thanks!

Why? The watch will stop when it winds down anyway.
You hack a quartz to shut it off if it's not being worn for long periods of time to save the battery but no need to hack a mechanical.

Probably incorrect terminology on my part... I'm referring to when you pull out the crown to set the time... It makes me cringe to watch the way some people handle their watches, especially when doing things like this. As I said, there' little wonder why some people have issues...

When I bought my IWC that has a7750 with the sec@6, the person who sold it to me told me it's best to keep the watch hacked to preserve the movement. I guess it's when, say I'm done wearing the watch after the day, and instead of just letting it sit for 24 hours, hack the watch from working so that the movement doesn't keep on working.

Ahhh, now that makes sense. Yeah, I always change the date at around 5:30 to make sure, unless I'm dealing with a cheap watch that I really can't care less.

Well, he's wrong. You are better off letting it wind down than keeping a constant tension on the main spring and on the wheels.

Is that the same for all of the mechanical watches? All of the watches that are in my watch box are hacked.
Also, I went to the 7750/7753 section and read your post on keeping the 7750. I never knew manual winding was not recommended for 7750.

Man, thank you so much!

dont wind or hack them (or IMO use the chronos)

be very gentle with them and cross your fingers

asian 7750 is a piece of junk IMO

I think it's fine. I've had 5/6 A7750s and never had a problem with any. There might be some element of luck on an unserviced one but I'd be confident of a serviced one.

I think calling it a piece of junk is unfair.
