Really nice build, great plating by Tommy as always; Domi did a nice job with the rep hands. There may be some more robust solutions forthcoming.
I use my LWO283 chrono functions all the time, without apologies. The decreased lifespan of the LWO or sooner servicing doesn’t worry me. The slippage is an issue with broached rep chrono center and aftermarket chrono center hands. Gen chrono center hands have never slipped on the LWO283 pinion in my experience.
Slippage of the hands is only one issue associated with the LWO 283 movement. The fact is that it is not a reliable chronograph movement, and even the AP caliber 3126/3840 (which uses gen hands naturally) exhibits design-related problems. So while your favorable experience with the chrono is well-noted, and entirely plausible, there are other issues which can occur other than visible hand slippage. For example, even the gen chrono gears are known to break, dislodge or drag and deplete the power reserve. I am speaking of the stacked chronograph movement design issue in general, having handled in excess of 100 of the AP 3126/LWO combined. I am not talking about owning 1 or 5 watches with the LWO movement. That certainly qualifies as owner experience, but I think that I have owned or handled enough a decent sample size to understand what I am talking about. These cases are also well documented on various forums.
So while I acknowledge your note that the hand slippage issue can be resolved by using gen hands, or painting the aftermarket or rep hands, or broaching it more precisely, the issues that are inherent within the stacked chrono movements are far more than hand slippage. You have to handle enough LWO 283 movements to understand or appreciate what I spoke about. Owning 1 or even 5-6 frankens and having zero issues with those validates your experience for those watches, but it does not change the design problem of the LWO283 in terms of chrono reliability.
QueTip is another guy who understands this implicitly. You may be fortunate enough to have no issues with your chrono, but you need to be aware of other owners who did, and potentially will and not be inconsiderate posting your experience in such a manner to give them a false sense of complacency to do the same. It is like an A7750 sec@12 owner telling another one with a dead movement that his is running exceptionally well, so therefore, the A7750 sec@12 movement is a wonderful movement without issues.
We need to differentiate between sample sizes of our experiences, the design facts, and also sensitivity toward others.
