ETA 2836-2 Movement Review & Information

The ETA 2836-2 movement is essentially the basic ETA 2824 with the addition of day-date functionality. The day change is also quicker on the Eta 2836-2, it’s considered instantaneous vs pseudo-instantaneous. The movement itself is also slightly higher due to the date wheel, than the 2824. Other than that they are very similar movements.

The ETA 2836-2 movement has a high beat rate of 28,800 bph which is in contrast to the ETA 2842 movement which beats at 21,600 bph.

 

Miyota 8215

I’m seeing that a lot of people are searching for the Miyota 8215 movement and for information regarding it’s viability as an Eta replacement. I wanted to throw together some basic info and specifications for you regarding this movement.

The Miyota 8215 is Japanese made, an automatic movement designed for wrist watches and used by many different watch makers. The Miyota brand is a member of the Citizen conglomerate. As we know most wrist watch makers can’t produce their own movements and this quality Japanese movement is a good alternative for many companies including well known brands like Citizen, Invicta and Jacques Lemans.

The 8215 movement is a 21 jewel movement with a left rotation (unidirectional) winding system. It’s accuracy is a modest -20 to +40 seconds per day, not amazing, but acceptable for most low end watches. One glaring disadvantage to this movement that may annoy it’s users is it’s lack of a hacking mechanism. The lack of hacking means it’s unable to stop the second hand movement when the crown is pulled out to the quick set time position. This movement has a 40 hour power reserve which is more than adequate for most customers.

Another disadvantage to this movement for some, will be it’s low beat 21,600BPH performance. This will make the watch ‘tick’ more compared to 28,800BPH that many are accustomed to.

Overall this movement is not a bad choice vs some of the ETA offerings, but it’s lacking in several key areas. I would stick with ETA!

Will ETA movement be replaced by Sellita and other brands?

As we’ve discussed in several prior articles ETA is reducing it’s supply to outside buyers. That is, buyers outside of the Swatch group that it’s a part of. Swatch has indicated that they must reduce outside sales as they can not produce enough movements for their own use due to increased demand.

Some watch makers will undoubtedly create in-house movements or acquire other watch makers that have their own movements. While others will need to start looking elsewhere for supplies. What options are there? There is another popular Swiss movement maker that will probably satisfy demands. That maker is Sellita which has new chronograph movements. It seems Sellita is well on the way to stepping up and filling the void in the market that ETA is creating. Read more

Hard times for Swiss watch makers and movement suppliers.

In the current economic climate we’ve seen many many different markets hurt, fail and even disappear. While we haven’t seen huge public bankruptcies and fallout in the Swiss watch industry, there is not much known about what’s really going on behind the scenes. These luxury makers aren’t nearly as public as for instance the car industry.

From the outside looking in, things may always seem to be going swimmingly for the luxury watch makers like ETA. We see the boutiques and the booming business, products seem to be improving every year and everyone is forming conglomerates. The glossy veneer of the industry has not yet faded away by any means. However it may shock you to find out that many famous watch makers are now dug in to a legal conflict with the biggest movement maker, Swatch, which ETA is a part of. The main issue is ETAs supply of movements and ébauches to brands outside of the Swatch conglomerate. We touched on this issue in a prior article about ébauches from ETA.

What are ébauches and why are they used?

So we all know that watch makers buy ébauches from companies like ETA. So what is an ébauche? The word ébauche is french for ‘blank’ and in the watch making community it implies an incomplete movement. Lesser known watch makers frequently have no in-house movements to offer their clients, but even the big names typically have very few in-house movements outside of their most expensive or newest models. These makers frequently buy ébauches from vendors like ETA to add movements to their watches, while focusing on style and design. For ETA this is slowly changing, because it’s owned by the Swatch group. As of 2010 ébauches are only being provided by ETA wholesale to the other members of the Swatch group. This means that more and more watch makers outside of that group will have to either develop their own movements or buy from other vendors. The cheap ETA era may be coming to an end as stocks run low.

ETA 2824-2 vs Miyota 8215

As most of you surely know, the majority of watch makers don’t have their own in-house movements. They usually purchase their movements from ETA, Valjoux and other firms. This became exceptionally common after the advent and popularity of quartz driven watches. Everyone wanted a quartz watch for their unparalleled precision, reliability and dirt cheap pricing. This forced the surviving watch makers to start buying movements rather than developing their own. There are of course exceptions such as the new Breitling B01 movement.

So I would like to give you a comparison review of these two extremely common automatic movements. These movements have been used in countless watches for many years. They are excellent movements and provide accurate and reliable mechanics for your coveted time pieces. We see the ETA 2824-2 movement in many watch makers brands such as Rolex, Cartier, Maurice Lacroix, TAG Heuer and Tissot. While the Miyota movement is common in lower priced watches from Invicta and Citizen running as cheap as $100! Read more

Don’t regulate your own watches.

It seems that many Swiss watch owners refuse to take their movements and watches in to be serviced by professionals. They seem to believe that accuracy can be achieved by adjusting the regulator screw +/- without a timing machine. It’s better that you either take your watch in for a proper service or just live with losing or gaining a few seconds each day. If your watch is losing a lot of time you need a proper cleaning/service.

Regulating ETA swiss movement is a lot more complex than it appears. If your watch is inaccurate beyond factory tolerance there is a reason. The watch probably requires cleaning, conditioning, oiling, greasing and inspection. You need to have a professional ensure that all of the wheels are free from obstruction. The hairspring must be centered and the last coil of the hairspring must move freely between regulator pins.

A timing machine is then used to regulate the properly serviced and conditioned watch to provide accuracy within the parameters of the particular ETA movement.

Genuine ETA 2836-2 Movement vs Replica/Clone 2836-2 Movement

The Asian clones of ETA movements are nothing new. They have been sold in cheap and high end replica watches for years. Some of these movements are very good, others are horrible. If you want the performance of a real swiss watch, buy a genuine watch with genuine ETA movement.

What if you’re buying used? How can you be sure the watch and movement are authentic? Well the answer is it takes years of experience to tell the difference between a high quality fake and a genuine watch. This little diagram will show you the difference of the movement between a genuine ETA 2836-2 and an Asian clone of 2836-2 movement.
