I received this sweet CR-220 Sea Lion that is running a nice 30 jewel 8305A movement in a small Seiko lot. Sadly this very cool watch is missing its back case. It even runs with a little help. The dial is clean the gold tone case is not too bad either. I am going to put a add up for a WTB and hope somehow I get lucky. I do not even know the watch number. The dial is marked 8305 8090T. What a beautiful watch it would be to restore if I could just get luck and find the case back. I have never seen a model like this where the dial is marked CR-220 Sealion. I am thinking it is early 60's

Both the dial and the movement itself are stamped 8305A. I do not even know what the rear cover is suppose to look like but I love the dial with Sealion stamped right on the dial. I probably will end up finding any case back that fits just so I can wear the watch. With the large size of the case I would love it if it has a large Sea Lion etched on it. I love Sea Lion watches like the M55 the M88 but the case backs are smaller and the Sea Lion emblem is smaller.

I just went through everything Ramon has and I did not find anything he had listed for an 8305A. I did not find any movements or what I really want which is a Sealion case for a 8305A movement Seiko? Wha6t did you see because I can not find anything.

I looked closer at the dial and it is an 8306 movement. I found the listing you found but in the description of the watch it states the watch has a 6309 case back on it! Man so close! I did find One single 8306 Seikomatic-R Sealion CR-220 on all of eBay in the Philippines and I was right the caseback is fantastic check this out.


Somehow I have the feeling finding one is not going to be easy!

Hey, 35 jewels - not bad ;)

It seems you already found a caseback picture of the correct SeaLion - I only have my 30 jewel M77 to show ;) Nice to see another SeaLion here.

The 8305 and 8306 differ only in the day display.

It's definitely an 8306 (8305 is date only). It is auto and hand wind.




Case back should look like this (without the scratches :()







I believe this is one of the oddities in that it has a roller clutch, rather than the Seiko magic lever system. Sounds like I really know what I'm talking about, don't it ? :grin:

Yes afterwards looking at the number on the movement under the glass what I though was a 5 ended up being a 6 then I found the whole model number of the watch is a 8306-8090 and I found a picture of the rear case. No wonder someone stole it off the watch it is a nice looking case back. I am just going to tuck it away and keep my eyes open for a donor watch. I love Sea Lion models. I find if you wait long enough almost anything will turn up.
I managed to locate just the rotating bezel and insert for one of my 7A28-7040/9 chronographs. Maybe one day.

I have the same watch except it is a Seikomatic-R 30 jewel but it is not a Sealion. Serial 7N8176 model number 8305-1010 I also have a Selfdater 24 Jewel M55 Sealion but it is from 1963 so the case back markings are the old style. It just has a 14095 on the outside and the bride for the balance is stamped 394 for the movement number. It serial number is 3D13898. I like the large clean looking dials on these models. I did not even know there was a 8306 movement. I am going to have to have closer look at the movement once I get caught up with some other stuff.

I know it's allowed to bump 5 year old threads but since the new forum software kicked in this is becoming rather commonplace. Myself I find it annoying but maybe I am alone in that regard.

I think the way the new software returns search results is the reason. Try searching for anything, you get the threads in random order and lots and lots from eons ago.
