Need Advise in Removing Tourbillon Movement (SeaGull maybe)


Question

I've been looking for a forum like this for a while. My Minorva Tourbillon watch has a hand that fell off. Now this is not the time or place to discuss the ups and downs of of purchasing an inexpensive tourbillon watch. However I do like to watch and love to have it back in my wrist. Issue is I cannot get the movement out. I opened the back and was unable to remove the movement from there then I was advised to try to get the moving out from the front but I'm having real problems getting the front bezel and Crystal off. I've attached some pictures they're not the greatest, I'll upload some better ones if needed but any help would be appreciated here. Thanks in advance. 
I thought about forcing the crystal out with air pressure, because all I need to do is just access the front of the dial. However then I realized it if I pressure the front crystal out the back display case will probably pop out first.

Alright so it works like this: normally you would have to remove the case back, the crown and stem and the pushers/buttons (sometimes you can remove the movement without removing the pushers). Afterwards the movement and dial should come out (sometimes you might have to remove 2 screws as well on the sides of the movement). Do you even know whether the watch is a front loader (movement comes out from the front) ?

Thanks for your response. I initially thought it was a regular back removed movement. I remove the back and took out the crown and stem, but the movement refused to come out the only thing it did was rotate. There were a few screws visible but I was unsure which one I would need to loosen if it was even possible to loosen the movement to remove it through the back. Someone that advised me that it's a front removal and I've been working on that assumption ever since. Would you be able to show me what the screws may or may not remove the movement from the back?

I'm talking about something like this not screws ON/INSIDE the movement. Some movements require you to rotate them so that they can be removed. You should post a photo of the watch with the case back removed.

Also, if the watch would be a front loader then does it have any space between the mid-case and the front bezel (the one that the glass is attached to) ?

There are no screw is attached to tabs as in the one you have pictured. There was a tiny what look like a cab under the front bezel in between the front bezel or Crystal casing and the mid-frame. That's why when someone had told me and maybe a front loading movement and made sense, however I've tried to open it up that way with absolutely no luck. I will post pictures when I have a few seconds. Thanks for your help.

I have not worked on worked on one of these movements but I looks like to me that It removes in the conventional way. The three screws I have identified are they by any chance half rounded at their tops so you just turn them to release the case ring. A closer pics of the movement might be better to give more advise.

The three screws are rounded. I'll definitely try your idea, just how many turns do I unscrew them?
I've included some more pictures that aren't the greatest but on my phone photos of the best I can capture.
(I don't know if that's what you intended, but I just realized the caption of a my post, I wrote advise instead of advice. But I guess you know what I meant.) Thanks again to both of you for taking the time to respond I appreciate it more than you can imagine!b93c8bcb4d3e749476c0b4c72218ae6b.jpg2b0a3c654b8cb25f9c814fb51eccd6dc.jpg5374bfca0d4b7f505b1370509e72cfc2.jpg

I'll say it again, you have to remove the crown and stem and perhaps the pushers as well. Whether it's a back loader or a front loader you have to do this first...

I can see 2 screws at the sides which might require removing... The ones that sit into those 2 spaces on the sides of the movement.

I did that. I removed the crown/stem, and the movement just rotated, but didn't come out. The pushers are not connected to the movement, but rather push up against small tabs that are part of the movement.

Does it wobble at all ? Sometimes you need to fiddle around a little bit to remove it (careful not to use excessive force).

Does the movement itself sit in a form of threaded recess inside the case ? (some require you to rotate the movement around until some tabs reach some spaces in the case and then it can be removed)

If you turn it to the side, do you see any space on the case ? Between a supposed mid-case and a supposed bezel and glass.

I didn't notice anything that would match any of those suggestions. However tonight I will remove the two side screws again and try your ideas and see if I have any luck with that. Thank you again I will keep you updated.

It looks to me like it comes out the front.

The milled bezel may unscrew or it may need a case knife to pry it off. Once it is removed you need to remove the stem and both of the recessed screws that allow the movement to turn when loosened. With these two screws removed the movement should come out the front.

That's how I would proceed.

Issue is it's not a screw-in bezel, and I've tried to pry it open, but I've had no luck at all. Couple that with the fact that I don't know for certain it's a front load movement......

Did you see the pics I've added? Would you still assume the three rounded screws need to be loosened?

To clarify, there is a small notch under the "supposed bezel and Crystal" but I've been unsuccessful in prying it open from there. Do you think the fact that there is a notch there is an indication that it's a front loader?

Just spent some time with the watch, and there seems to be a lip or groove preventing the movement from coming out the back. Seems I need to remove the front bezel and Crystal. I already got three cuts last night trying this exact thing.... Oh well....

Had another look this morning these must be the screws too loosen. Remove the stem and it should drop out. DO NOT UNDO the SCREWS I originally suggested or it will damage the movement.

Thanks, I figured as much. I got it open via the front, as it doesn't come out even with those two screws removed. Thanks again.

    • I think Earl Gray is an acquired taste. I hated it when I first tried it. Now I find it tolerable. Eventually I might find it ok. 😂 But what do you think of tea used in confections and other foods. Like matcha cakes 😖, Earl Gray cheesecake 🤪, duck smoked with tea leaves 🤔, etc...?
    • Hello Not really a watch question, however I thought I would it it a try. I have a couple of Silver Beer Mugs that are tarnished and all I have to clean them with is the L & R Ultrasonic Watch Cleaning Solution (ammoniated) and a ultrasonic machine. I also have the L & R Ultrasonic Watch Cleaning Solution and an Ultrasonic machine. Does anyone know if I can use these two products on the silver beer mugs or should I get another type of cleaner> Also should I be diluting the cleaning and rinse solutions?  Thanks in advance for any help that can be provided.

    • Hi JDM - Thanks for the detailed reply. The Bezel only looks like a rotating time ring, but it's just a "faux" divers watch, only rated to 50m. I think the Seiko "Solar Power" version actually had a rotating ring and Tritium on the hands and numbers and was rated to 200m or something. But, the bezel is fixed. Also, there are no "indent" or any indication that you could use a Snap Back knife to open the bezel. If this is not indeed a screw off bezel (using a screw type base wrench), then a 4 blade bezel tool is likely the only thing that will remove it. Then I'll need to figure out how the stem is removed so I can remove the whole movement to get to the Cap which I assume is underneath. Other owners on some other watch forums have reported the same experience I had with my Lorus/ Seiko 851 model, the Capacitor fails after only 8 to 10 years and nothing like the "promised" 80 years (Life Time Warranty they refuse to obey). Quite a few owners wrote that they had the Capacitor replaced, but no details on HOW. Read my response above to "watchweasol". There's been some conflict about which capacitor to use as well since the original 2023 24T / MT920 was discontinued 30 years ago (probably the reason all these Lorus Solar watch never met the 80-year promise. Supposedly the replacement Cap is a 3023 24T now. The word in some forums is that this Maxell Cap will last 30 to 40 years. The Seiko Kenetic watches supposedly also use this same Capacitor. Have you ever worked on the Seiko Solar version of this Lorus? Thanks.    
    • @watchweasol - I  know that was the Seiko "company line" for both the Seiko and Lorus branded "Solar Power" versions, but there are an awful lot of folks that bought both and found the Capacitor died, like mine, only after 8 to 10 years and did have the Capacitor replaced with at first the original 2023 24T version and then the 3023 24T, which is apparently a much longer lived replacement. Seiko's "promise" of an 80-year life for this Capacitor was all hooey and likely the reason Seiko quickly dropped both their own branded model and the Lorus ones after just 10 years on the market. Both Seiko and Lorus (who is no longer in North America) refuse to honor the "life time" warranty. One of the reasons I now trust Casio more than Seiko for warranty promises. The movement in the Lorus is literally the exact same one that was in the 3 "Solar Power" Seiko mens models, a Seiko NA tech admitted that to me almost 30 years ago when mine stopped charging. I bought it new in 1986 or 87, and I still have the original paper manual and box and "Life Time Warranty" card (good for nuthin'). I've been a watch and clock "collector" since a teenager, prefer early American pocket watches, but who doesn't love early American MADE and Japanese and Swiss made wristwatches? So I've also collected all the tools a watch and clock tech uses, many pretty vintage too, and learned how to work to a certain degree on most any watch or clock, restoring and fixing, to my limits. I already have that (another version) Bezel removing tool, am just trying to confirm that the bezel is NOT a screw on, or absolutely IS a press-fit. Was hoping to find someone that has either worked on the Lorus version or the sort of same looking Seiko versions that also had the one-piece "tub" body. The Bezel only looks like a rotating time ring, but it's just a "faux" divers watch, only rated to 50m. I think the Seiko version actually had a rotating ring and Tritium on the hands and numbers and was rated to 200m or something. This Lorus/Seiko is an odd-ball and there is absolutely no repair info on them, so that makes me want to fix it more myself.
    • Very, very nice production.  Really outstanding walkthrough!
