Hi

I hope some one has kept a copy of the ETA pdf of the specifications for the Auto 36,000 Hi Beat movements, i.e. ETA 2337/38/39 possibly the 2832 and 2826, as I think they are in the same family.

I have gone to the technical section on ETA and the information is no longer available

I have seen them around here recently, so somebody must have a link.

I have a hard copy, but no way to scan it.

The following information is from my copy:

2819 - 36,000 bph version of the 2801
2806 - 36,000 bph version of the 2804
2817 - 36,000 bph version of the 2816 (a day/date 2801)
2839 - 36,000 bph version of the 2821 (dateless automatic)
2826 - 36,000 bph version of the 2824
2837 - 36,000 bph version of the 2836
2838 - 36,000 bph version of the 2834

All hand fitting and dimensions are the same between the 28,800 and 36,000 bph versions.

Further, all parts, except the second wheel (#227), escape wheel (#705), balance assembly (# 721) and hack lever (#9433) are common between the 28,800 and 36,000 bph versions. (Even the mainsprings, a fact borne out by the Bestfit catalog.)

There were a number of movements in that family, including a number of 21,600 bph versions: (most of the repeated calibers for the same functions are different mainplate sizes, 11-1/2''' and 13'''

2800 - 21,600 bph version of the 2801
2802 - 21,600 bph versions of the 2804
2803 - 21,600 bph versions of the 2804, 13'''
2808 - 21,600 bph version of the 2816
2809 - 21,600 bph version of the 2816, 13'''
2820 - 21,600 bph version of the 2821
2822 - 21,600 bph version of the 2824
2823 - 21,600 bph version of the 2824, 13'''
2828 - 21,600 bph version of the 2836
2829 - 21,600 bph version of the 2836, 13'''
2805 - a 28,800 bph date manual (same as 2804, 13''')
2807 - a 28,800 bph date manual (same as 2806, 13''')
2810 - a 28,800 bph day-date manual (same as 2816, differences unk)
2811 - a 28,800 bph day-date manual (same as 2816, 13''')
2812 - a 36,000 bph day-date manual (same as 2817, 13''')
2825 - a 28,8000 bph date automatic (same as 2824, 13''')
2827 - a 36,000 bph date automatic (same as 2826, 13''')
2830 - a 28,800 bph day-date automatic (same as 2836, differences unk)
2831 - a 28,800 bph day-date automatic (same as 2836, 13''')
2832 - a 36,000 bph day-date automatic (same as 2837, differences unk)

Thanks, I knew you would come through..

So if I can follow on from this, if the movements was a 2837 Chronometer, then I could deduce from the ETA2801/2824/2836 pdf spec sheet, that it would share all the "chronometer" specs as per the document??

I will tell you why I am interested.... I have at least 6 ETA2837 and will bring tham back to spec and release them as specials.

I shall assume that all ETAs were classed in a similar manner as they are today (the names may have changed, but otherwise, the same).

Therefore, a chronometer 28xx would have originally been adjusted to chronometer specs.

Got picture?

We love movement :-x:-x:-x:-x too.

Got it - thanks... I have a recent ETA spec sheet from the 2824-2, so those Chronomter details should hold.

I am sending my watchmaker a couple of movements to get new life put into them

In theory, with all other things being equal (that they are not) 36,000 beats are more accurate.

But all the other associated extra stuff, they tended to die due to ecoomics and the rise of the venerable 2824-2

Favre Lubra 401 (I think that is the number) is a recently released hi-beat movement and of course the ledgenary Zenith El Primero (what ever teh name is) stands at the penical of current accurancy

Essentially faster the beat the more accurate the watch. But then the pursuit of accurancy is a very expensive game - big bucks for just incremental gains.

Not sure what you mean by "vintage". I supose they are vintage

The ETA high beat movements were made, (as I understand) in the 1970's and 1980's.

So I suppose it depends on how old you are what vintage means. So they are about 30 years old - from memory that is vintage 30 years plus - so they must be vintage.

I get about 25% success rate. That means the watchmaker throws away 3 out of 4 movements. Not the easist way of getting a movement. But tell that to a collector - ha ha

Personally I think they are under rated. But I think Enicar and Doxa (the real Doxa before the Sub the elegant dress watches that everyone forgets) are underrated... call me crazy

no not at all.

Zenith in their chrono is a highbeat movement

Favre Lubre have or will relase a hi beat movement the 401, that has an extraordinary long power reserve.

There could be more these are the only ones I know of.

There is a fabulous website

http://36000bph.com/

it is fascinating. It is a pitty there are not more people interested.

My small group of High beat movements will see the light of day soon, so I will try to get an owner to doa review - possibly 60 days time

Mate,

A tricky question. The ETA high beat movements share the physical size of the family. That is they are physically the same as the ETA2824.

Provided the MilSub case is designed to take an 11.5"' movement like the ETA 2824-2, a simple drop-in-drop out.

If you are referring to the OWC MS-5517, this is a question for the Sales Forum or a personal email. I know the moderators are quite strict about these things.

As I mentioned, previously they are vintage movements. They are good, but you need to have a few, just in case you need spares. Basically a similar body to the 2424, but it has all the Chronometer refinements and the various wheels that were mentioned in a previous post.

Did any one find out about the Favre Leubra 401??

Favre Leuba FL 401. Have a read it is fascinating.

Also the limited release A schild 36,000 movement that I suspect is the AS1920 - yes we have been talking I chose ETA FL choose AS -

JUST JOKING...

I can't figure out what AS movement the limited FL watch uses, since they say it is a manual movement, and the 1920 is an auto.

Where is the lysanderxiii of A. Schild?

Hey Dan,

Good to hear you're making progress with your 2837 project. I'm looking forward to seeing the results.

I was unable to get the Zodiac 86 movement to fit the Zenith prototype diver case (so close, yet so far), and am now working on getting the AS1920 to fit. Got my first ETA (Zenith) 2832 coming, and will try to see what it looks like compared to the 2837.

Wonder what all those other ETA high frequency movements were put in?

Your the man....

I am sad t here the Zodic did not fit.

I am attaching some photos of my Zenith 2832. It need to be serviced and I need a case, but I have one, and looking for the right Zenith Case

Yes where are they. If you find them let me know I have a good home for them.

Currently my watchmaker is working on 2 x 2837's but he could use more
