Benrus Watch Movement


Hello All,


I am new to this forum and relatively new to repairing watches (so please don't bite!).


I have repaired a couple of cheap watches before and both have worked out fine so decided to try my hand on Benrus I have had for a couple of year and am quite fond of.


All was going well and then I had a pet related incident whilst opening up the mainspring barrel. By the time I had found the barrel (cap, arbour and mainspring conveniently ended up in my lap) it had been damaged and some of the teeth destroyed.


I have tried to identify the movement in order to figure out what part to try and find (picture attached, apologies for the poor quality) but really struggling as it doesn't look like any other Benrus movement I have seen anywhere online.


The watch has 1974 on the back (looks like a "length of service" gift awarded to someone by the inscription).


I bought it from ebay and the seller doesn't know anything more about it. If more picture of any more of the parts would be useful please let me know.


I'm just hoping that someone will be able to help.


Thank you in advance.

I don't now if its a fake . I just recognize the diashock and the balance bridge . They are similar looking but the 5740C is not the right movement .looking more like the Seiko 66A


Defenetly a seiko movement but which?

What is the size of it ?

Thanks Geo.


rogart63 I see what you are thinking, looking at the Seiko 5740c there are some similarities there. Are we guessing this is a fake Benrus then?


Regardless i'll still like to repair the thing. Interesting though.

I posted some pics of an original Seiko 66 and a UTC on a Seiko specific FB group. Only difference is that Seiko stuck with their full plate style where the UT movt had a more traditional separate barrel bridge / train bridge set-up and additional jewels.

Brilliant thank you to all for your help. I do hope its still a "nice" movement once I have finished with it!!!

Have found a replacement barrel for the 66a online so will give it a go.

Thanks again.

Benrus was an assembler.  Not a manufacturer. Movements  were sold and rebadged under  several  names. Among them UT and master time. They  can be found in several  second tier watches  such as benrus, eltra, Clinton  and westclox.

      I am considering selling leather watch straps, but I have a question before I blindly go ahead and produce a bunch of them.
      I am wondering if anybody who has worked in the industry for a while can tell me what the most common sizes are of strap pins or lug widths?
      I would really appreciate it. Thanks in advance.

      Greetings all.
      I recently acquired a moderately old Benrus 3-Star Automatic wristwatch. It's a #7026 Series.
      I believe these are from the 60's - though I don't know much about them.
      On the back of the case it says "open through crystal". Which makes me think that the Crystal should be removed using a Crystal Lift - and the movement lifted out through the bezel.
      Of course, the stem (presumably two-piece) would have to be separated prior to - or during the operation.
      BUT - after some googling - I have also heard tell - that the case-back should be pushed out by pressing on the crystal with thumbs. These seem to be incompatible methods - but I really have no idea - as I have never seen a case like this. 
      Does anyone have experience with this type of case from Benrus? I can post pictures after I get home - if they are needed.
      Many thanks!

      I picked the up the 1945 Bulova Cadet as a non-worker on eBay, then I received a parts lot that had a Westfield case and dial. Of course, I had to get a 1940 Westfield Trojan cousin movement for it. 

      Unfortunately, I didn't notice til this morning that the replacement Westfield had a curved dial whereas my case had a flat dial and it doesn't fit. Oh well, guess I'll have to buy more watches.

      Hello Everyone.
      I need some help with repairing my Emporio Armani ar-1922.
      I've watched some videos on YouTube but none of them resemble the movement of this particular watch.
      My first problem is removing the stem/crown. I cannot see anything which looks like it will release the stem and I don't want to poke around inside it any more for fear of creating any damage.
      Any help will be much appreciated.

      Hi guys! I have a watch that uses a Ronda 751 quartz movement (see pic). For those unfamiliar, it’s a small tonneau shaped movement - usually a woman’s size (5½ x 6¾ linge and 2.5mm thick) with the following specs:
      Linge Size: 5½ x 6¾, 2.50mm thick
      Hand Size: 120/70
      Stem: 401-1237
      Cell/Battery/Power Source: 379
      Tap Size: 10   I’d like to replace it with a mechanical movement: I started off looking for a direct drop in replacement but it’s proved very difficult. I haven’t found any modern movements with the same dimensions (although to be fair I haven’t had much luck finding a comprehensive listing of modern movements available). As far as the vintage movements go, (from here: http://www.ranfft.de/cgi-bin/bidfun-db.cgi?10&ranfft&0&2uswk) the ETA 2480 (http://www.ranfft.de/cgi-bin/bidfun-db.cgi?10&ranfft&0&2uswk&ETA_2482) is a good example of the vast majority of what’s available— the right dimensions but 1mm too thick. And for a 2.5mm movement, 1mm is a ton.    The Tissot 530 (http://www.ranfft.de/cgi-bin/bidfun-db.cgi?10&ranfft&0&2uswk&Tissot_530), and Enicar 672/678 (http://www.ranfft.de/cgi-bin/bidfun-db.cgi?10&ranfft&0&2uswk&Enicar_672) are the 2 that seem closest but they are still a half mil too thick. And worse, even if it fits, where would I even begin looking for one?   Does anyone one have any knowledge of a movement that would work or one I could modify a bit to fit? Or any idea the best place to look??   Thanks in advance for the help and I love the forum!!

    • Hi sorry to trouble you again before i try and put a bit more force just want to make sure i explained myself right, the part i am trying to take of is just below the snail i know the one near the top with a pin on is called a gathering pallet is the one below the snail also called the gathering pallet which is on the hour hand. Thanks Willow
    • Also, just my opinion, but from looking at your video, the freedom of movement which you are getting from the barrel when turning on its arbor is fine.
    • I wouldn't be surprised if it makes little difference having that score there. It will be a "plain hole" in the jewel, so the walls are flat and parallel, so the ring will simply not touch the jewel. Unless of course the groove is the same width as the contact area with the jewel.
    • No, I haven't yet received the smoothing broaches, but once I've tried it I'll let you know the result. I'll be going very easy and I'll try not to overdo it. Hopefully it will make the barrel spin more freely around the arbor. CousinsUK doesn't have the barrel and cover as spare part so hopefully I won't be making a mess of it. I guess as a general rule it is better not to fix it unless it is broken, but in this case I'm just too curious to see what it's going to do.
