Thank you so much. You are a big help Lysander.

I am eyeing a Baume & Mercier based on the 2895-2, for a dress diver.

I have not seen any reviews on this watch, the Baume & Mercier MOA8124.
It looks very clean, and uncluttered, but I was unsure of the movement.


Thank you again,
Ilham

I'm new to this hobby, catching the watch bug only three months ago, and I have to say that this is the most informative thread I've read to date.

Thank you!

I'm going to keep studying and keep saving. I've yet to pull the pin on my first "nice" watch, and the more I read, the higher my savings goal goes.........

My GF's dad has a very similar watch (Capeland not-S, on strap) and it has provided reliable trouble free operation for about 6 years now. Maybe a little more. The winding efficiency is a bit low, but that's going to be true of most any 2892-based movement.

Since the second hand is small on this model, any stuttering that does occur would be less noticeable than, for instance, a Miyota movement with indirect seconds in a watch with a center sweep seconds hand.

Folks please,..I want to use this 2895 movement in an old watch replacing a worn out subsecond movement. One thing is critical..I need to know this: What is the distance in mms from the center of the canon pinion to the center of the seconds subdial arbor? They [ the 2895 ]are too expensive to experiment with not knowing tis critical detail. thank so much. Ben

That information as well as all other critical casing dimensions is available at WWW.eta.ch > Bienvenue > Support Center Portal > Technical Documents > Search All Movements > 2895-2

Hi lysanderxiii,
I see you & others have referred to the ETA web site. I attempted to access the technical area as described; alas I could not access the portal with out registration.
Registration appears to be set-up for eta customers in the watchmaking industry and not for amateurs. Is there anyway non-professional can gain access?
Regards,
Peter

If you click on the "technical documents" link, closer to the top, left of the page (immediately above "Welcome"), you can access them without logging in.

The small seconds in this movement, unlike older movements with this feature, are run off the minute hand. Sometimes, it is reported, they stutter.

Bumping this thread back to life because of a question directly related to this post: Is this stuttering repairable? One watchmaker says no, another says "just service it, it'll be fine."

Any watch wtih an indirectly driven seconds hand will see a bit of stutter, and this includes the seconds hands of chronographs (that use lateral engagement gears) and vintage high-end watches made when a central seconds hand was an innovative complication. For example, my 1946 Jaeger-LeCoultre ref. 2953 uses the caliber P450/4C, which has an indirectly driven central seconds hand. The fourth wheel is in the usual spot for sub-seconds watches, 90-degrees clockwise from the crown.

Here's the JLC caliber 450, from the Ranfft site:

The fourth wheel is at left, just to the above-left of the balance wheel. It drives the third wheel, which has an extended arbor out the back and a wheel that is used to drive the seconds hand, using a pinion in the middle of the watch. That big wheel on the back is what gives this watch a central seconds hand. Note the copper spring that is attached to the back of the central bridge. It is adjusted to put a slight amount of drag on the central seconds pinion so that it does not stutter. Adjustment is critical--too much drag at it will reduce amplitude and reserve, and too little will allow stutter. Personally, I'd rather have a bit of stutter.

But the 2895 has the same flaw as the JLC 450 above--it is a movement designed for one presentation used for a different presentation. In the case of the 2895, though, they had to add several intermediate wheels to work the gear train around to the 6-O'Clock position. Other companies did it better with their modules (the Ja Joux Perret 3532 comes to mind, though at a higher price), but I don't see any way to adjust the backlash, or to provide adjustible drag to the seconds hand.

Usually the small size of a sub-second display, with typically a 4mm long hand, makes 'stuttering' hard to discern, compared to say a second hand 15mm long.

For example, one second is 6°, so a 21600 bph movement has 1° of second hand movement each jump. If you have really bad stutter, say 1/4 of the total movement, with a 15mm hand the tip overshoots .065mm, or about one tip width. With a 4mm hand, the tip overshoot is less than .02mm.

As stated the way the seconds hand is driven may result in some observable stutter. If so it's not broken or in need of service. I would think that any stutter would not be visible on the tiny seconds hand of a 2895-2 movement.

This is a great resource for less informed watch enthusiasts. Thanks for being here! I own a very nice Hamilton Pioneer with a 2895-2 / small second hand movement. Unfortunately, I dropped it. Now I need to replace the movement but I don’t know what’s the Hand Height is for this particular movement. I know the 2895-2 is available in a few different hand heights. I don’t know which I need. Can anyone help me with this? Rob

The ETA 2892 A-2 is one of the best automatic movements ever developed. The 2895 is simply that movement modified to have a small seconds hand instead of the center seconds hand of the 2892. It has two more jewels because of the modifications. I have several watches with the 2895. They are superb movements.
