SQAULE OCEAN DIVER WATCH

 

Hi everyone. I am in the process of looking for spares for a SQUALE watch. I was at work and a colleague heard I did watches as a hobby and pulled this watch out of his drawer and brought it in. I have never heard of the brand but after some research I have found out more about te brand. Very cool indeed.

 

I need to repair/ polish or replace the glass and relume the hands and service and replace the battery and strap on the watch. I have not yet opened the retainer that holds the glass in but after removing the bezel I was wondering if this is a domed glass with a tapered edge held in place with a tapered retention screw ring or is it indeed a specialised bit of glass that has a flat lip on the bottom that this retention ring sits on to seal it against a rubber seal. I assume it would be the latter given that the watch is rated to a 100 atmospheres.

 

Has anyone worked on these watches or replaced one of these watch glasses before? Any pictures? If it is a specialised form I can see me spending many an hour polishing out the scratches.

 

Many thanks in advance.

 

Andy

Never replaced a Squale crystal but i have seen a few. They have a special form so you need to find the right one. Squale is a good company so you could check with them. Maybe the crystal on the newer model is working. http://www.squale.ch/squale/

 

If i remember right the crystal is a little like the Seiko 7c43 but thicker.

That would take hours to sand down and take all those scratches of. I would replace. And it's domed which makes it much more difficult. 

With scratches like that it takes me 15-20 mins the most to perfectly restore a crystal. 10 mins with paper discs on a rotary tools, and 10 more mins finishing with diamond paste on a felt wheel. Including tools changes, washing, etc.

If you're going to polish.. cool the part down frequently.

Don't depend on the touch test but dunk the thing in water for approx 30 seconds.. a minute is better, when it starts to get hot.

Heat builds up and takes time to dissipate. If you don't keep it cool it will break.

The crystal is what makes these watches special and if you don't get the thick one the watch will be so much lesser for it.

If during polishing a crystal gets so hot as described above, then something is very wrong with the abrasive, speed, pressure applied, or a combination of  these.

Starting with 380 / 600 grit wet paper on a 5 cm wheel, it's actually almost impossible to significantly heat up a crystal, considering the frequent dips in water needed for the abrasive to work the best. Then with diamond paste polishing no water is used, still the friction is small and will produce not much heat really.

For these reasons it is pretty safe to polish a crystal with the nylon gasket still in. As opposed to case buffing or polishing, where if you go hard and fast the gasket will burn.

A few pictures of the Squale restoration. Thank you to everyone that replied and gave invaluable advice. Unfortunately the coil is knackered so watch doesn't run so have started another post on this forum to try and resolve this. Glass or plastic came up a treat. Had issues as the old battery was left in the watch for eight years and it leaked acid all over so corroded a number of bits and bobs but managed to source replacement parts for this. Didn't check the electronic circuit as I was assured it was running when it was put away by the owner. Shame on me.

      Can someone please explain watchmaker service mark interpretation?

      By Waggy · Posted

      All I do is use a fine marker (sharpie) to put the service date on the back cover, this way it can be removed with some IPA and does no permanent damage to the watch. I'm in two minds about the whole service marking thing, sometimes it's good/bad to see the markings on the watch case back as you know it's been worked on and vice versa. However, if I took my car in for a service and the mechanic scratched some code into the housing of my engine I wouldn't be too impressed. Hence, I think my sharpie solution is a reasonable compromise.

      Movement holder made with 3D printer

      By Waggy · Posted

      hmmmm.... maybe there is a way to skin that cat 🙀 let me think on it... unless anyone else has any ideas? I left the opening in the side of the base and ring quite large to maybe allow you to grip the crown, but appreciate this may not always be possible, especially for small movements where the crown will not extend past the outer wall of the holder. I noticed this also, but after using the holder for a while I noticed that the ring/holder began to wear into shape (rough edges/bumps worn off) and the size became closer to the desired movement OD. Maybe with some trial and error we could add 0.5 mm (??) to the movement OD to allow for this initial bedding-in?

      Vintage pocket watches from e-bay (winding stems needed)

      By Mallard · Posted

      Hi nickelsilver, thanks for the great explanation and the links! I'll take a good look in the article.  Especially this is great news to hear! Looking through forums and youtube videos I was informed to 'fist find a case and then fit a movement for it'. But seems that's not the case for pocket watches at least?  I guess I should be looking to find some 'male square bench keys' for now. I was thinking of winding the mainspring using a screwdriver directly, but I found a thread that you've replied on, saying that it could damage the spring.

      Murks, The rate and amplitude look OK, and the amplitude should improve once the oils you have used get a chance to move bed-in, also I notice that you are using default 52 degrees for the lift angle, if you get the real lift angle (assuming it's not actually 52) this will change your amplitude - maybe higher, maybe lower. I notice that the beat error is a little high, but not crazy high. At the risk of upsetting the purists, if the balance has an adjustment arm I would go ahead and try and get this <0.3 ms, but if it does not have an adjustable arm then I would probably leave well alone. Just my opinion.
