This was a rather unexpected purchase for me a few weeks back, a Jenny Caribbean 1500 dating from around 1969.

The Jenny Caribbean 1000 is (arguably) the first watch rated to a depth of 1000 metres, this is the slightly larger by 2mm, 42mm Caribbean 1500
It was offered to me by a friend and at the time I knew nothing about Jenny's. Luckily there is plenty of information regarding their history here and on the Internet and I really liked the look of this watch (I love vintage divers)
My friend sent me the watch to look over and at the price I got it for, couldn't refuse!
Although it was running it wasn't in the best of health, gaining around 10-15minutes a day and randomly stopping. Hand setting, date changing were all fine and being an ETA movement I knew it shouldn't be a problem to put right.
The case, bezel, hands & dial were all in good condition apart from a small mark on the dial from a previous service I presume.

So, after handing over the cash I set about making her ship shape.
I bought a new barrel/mainspring and a new set of gaskets, 4 in total & into Jenny I dived ;)

The bezel clipped off nice and easy, revealing the screw down retaining ring.

Now I had to make a tool to unscrew the retaining ring. I had a couple of spare bits for my Jaxa wrench and set about grinding them down with my Dremmel. Crude but perfectly effective.

The ring was unscrewed with no drama and revealed the first gasket that was a perished mess.

With the ring removed I was able to lift the 5mm thick acrylic crystal revealing the next 2 gaskets that were in good condition.
To release the movement you have to separate the stem which is a split stem. This was done by inserting a pair of side cutters between the case and crown and slowly closing the jaws allowing the bevel of the side cutters to safely separate the 2 halves.

At this point I encountered a problem, the movement wouldn't budge. It was jammed solid into the case. This was rather unexpected as every bit of information I had about the Jenny's suggested the movement ring on these dries out and shrinks...Not this one, it was solid!
So I put a new blade in my scalpel and started cutting around the edge of the movement ring. It is a metal ring encapsulated in a rubber type material. After half an hour or so, there was movement. Finally I had the movement out and realised by the remnants of goo stuck to the case, the movement ring had bonded itself to the case. Maybe through heat, I have no idea?
Here you can see where it was attached to the case.

With the hard part out of the way I continued to disassemble everything including the ETA 2724 movement. The ETA 2724 was ETA's first high beat (28k) movement and this is indicated on the dial by the words "Hi Swing"
It was bone dry and plenty of dirt flowing around. This hadn't seen a service for a long time!


Everything ready for cleaning.

Dial cleaned using cotton bud a mild soapy water. Really difficult to capture the beauty of this dial, it has little reflective speckles in it and reflects wonderfully.

Everything cleaned and ready for assembly. I stripped all the rubber material from the movement ring and replaced it with tape.

New gaskets fitted :)

And here she is. The movement has been regulated and is running superbly accurate. I will pick up a nicer strap for it when I get a chance. It's been pressure tested to 100 metres as the machine I use only go's that that. I will take it for the 1000 metre test though, I'm confident it will pass ;)

It's a shame I cant capture the real beauty of this watch. Such a lovely dial and the bezel compliments it perfectly :)
I love my Jenny!

Thanks for the great comments guys.

Today I set about sorting the horrendous strap out. The Caribbean has flared lugs so I had to adapt a bracelet I had in the cupboard. I took a file to the end pieces and although they ain't Rolex spec I think it looks pretty damn good!

Great write-up!  That dial is in excellent condition considering the age of the watch.  The methods used to make a watch water tight to such a depth are quite interesting too.  Was it difficult sourcing such an odd sized crystal though?

The crystal wasn't replaced, it's original ;)

Very nice watch and work. When I saw the monocoque case and the name Carribean it immediately reminded me of the Philip Watch that my dad recently found again and gave to me.
So I checked and the relationship is documented on the very home page of Jenny [emoji6]

      Like losing Ranfft. That was a wake up call. We took his website for granted. Miss him terribly.

      Its 4 o'clock in the morning here in the Uk, i cant sleep, i dont sleep, not much ever really. My brain never shuts off to rest, I'm just a constant thinker, i have to be very tired to be able to sleep,  i guess eventually it will be my undoing and my health will suffer because of it I'm sure. But while I'm here i want to get as much out of life as i can, and give as much as i can, to help,maybe to make a difference to someone's life if that is within my capability,recent events have made that need even more clear to me. I'm not sure where I'm going with this or why i bring it up , or if its relevant to want i want to talk about its just in my head right now. What i do want to talk about is something thats been on my mind for ages. I like to be prepared,  I'm not fond of surprises because surprises take control away and i am a bit of a control freak at times. This forum, Our Forum if i can call it that, is here because of two reasons. The guy that created it and keeps it funded and the people that joined it.  Without either, it would not exist, and lets face it one day it won't ( I'm a realist and i talk about things others dont or who are afraid to in other words folk that dont particularly prepare for the inevitable). How many of us visit here regularly ?  How many among us almost depend on the forum as a way of socialising because they are stuck at home and how many of us has it become part of a daily routine to check in and see if they can offer advice or get help with something they are working on or just to have a chat and engage in some banter. The members here are in the thousands and thousands have disappeared over the years many had just a fleeting visit. But there are a good few of us that know each other quite well and visit regularly. I dont know about you but i wouldnt want to lose that communication with you all, in all honesty it has become an important part of that side of my life and helps to feed my passion for all things watches. Some of you may think differently and thats ok, some of may stop and think # what would i do " Without Our Forum " #

      Gamblin Gamsol for cleaning?

      Naptha appears to be a general name and its content can be varied depending upon what it's specific use is. Lighter fluid as an example can be light or heavier also with other ingredients to help it burn. Try sesrching for benzine ( as opposed to benzene which is linked to causing health issues ) . There are other fluids such as ethanol that you could try and also methylated sprirts, mostly ethanol with a small percentage of methanol added. Experiment with any new chemical to see how quickly schellac dissolves in its presence. I have tried a few things but hexane is not one of them, i understand it does evaporate very quickly.  Be sure sure to check out any safety data on chemicals you try. Toxicity of fumes and flash point information, ultrasonic machines can heat up fluids even without a heater function. And of course always ask here for personal opinions when trying a new substance.

      What tools does ebay have to offer this week.

      By GuyMontag · Posted

      I have that set and really like it. I prefer that crystal holder over the one that came with my Bergeon claw tool and any time I use the claw I use this one instead of the Bergeon one, just an additional bonus with this tool.

      Movement inserted from crytal side

      Is the Roamer not a split stem? I'm confused on your how your case is put together. If it is a front loader where is it you are putting the case screws? I love me some Roamer, do you have any photos?
