As far as the dirtyness is concerned : Ziggy mentionned that and you're right JJ saying that it's not worth having a low beat serviced to be sure you get a perfect movement.
In fact I'm wondering if today's low beats are still concerned by this remark, knowing that they disappeared for a while (we had not seen them during a certain time until the HBB came out).
My conviction is that they are just from an other manufacturer, the same way there are different high beat and low beat manufacturers.
My 2 HBB are both low beats and look different from the finishing point of view.
Same remark applies to my high beats.
I have owned quite a lot of high beats, and 3 low beats (including my 2 HBB). None has died, none has had major issues, and which is obvious is that we do not have more testimonies about low beats meeting more problems than the high beats
these days. I am really convinced that the past discussed unreliability of low beats... well, is past
Things evolve, and
I guess it's more a question of cost than reliability.
All problems which we see reported are common to both : chrono not resseting, stuttering seconds hand (I had this on my first OCC, not on my second), small minute hand not resetting. These are most common complains appart from the D.O.A. movements.
Each and every rep collector has his priorities on movements. Wanting a 28.8 k is a step I fully understand, but I personally don't think it makes a huge difference. We're talking about subtle things.
The aspect of the movement is, for me, more important, as it affects the visual flaws on a rep, which are the first to be remarked when reviewing. In my approach it's as important as a correct DW, a correct dial or whatever.
All in all, I'm trying to fight against the idea that low beats are crappy movements, just because I'm convinced of it. I have no technical argument to oppose, as I'm not a watchsmith.
Remaining 7750s in my collection :
- 2 HBB low beat
- 1 Porsche Design high beat
- 1 Baume & Mercier Riviera high beat
- 1 Breitling BB high beat with sec@3
- 1 IWC Portofino with high beat
- 1 Montblanc Sports Chrono High beat
My humble technical contribution to the low beat / high beat discussion is visual :

Back to the HBB topic : I would be more concerned by the different level of finishing between manufacturer 1 and 2 than by movement beatrates.
My second HBB (Polo Gstaat L.E.) has real ceramic bezel. I paid less than 300 for it (must be lucky

), whereas dealers like Angus continue selling the bezel alone for 258. Different ceramics ?
My very conclusion about all of this : if you look for a cheaper solution, you won't be disappointed by low beat and/or manufacturer 2. These reps are one step below the manufacturer 1 reps, but the price difference is worth thinking about. And one step below does not mean bad... at all.
