New here. Nixon watch question


Recommended Posts

Hello,

I am an amateur.  I like to tinker with jewelry and my own watches, but I focus on electronics mostly. 

I have this Nixon "Comp" watch I am trying to replace the battery in.  I cannot see how this back cover is supposed to come off without taking off the straps.

The straps have a Phillips shaped thing holding each four sides of the straps on.  I suspect they may be riveted in somehow.  Because when I can grab enough meat of this "screw"(for lack of a better term), it doesn't seem to turn much or be coming out at all. 

It's unusual that they would not leave a way to get the straps off, to remove the back cover, to replace the battery.

I am wondering if anyone has seen this/these before or has any input.

pictures enclosed, back cover screws already removed in pictures.

Hi  I have had a similar watch some time ago but I was able to work the back cover off sideways leaving the straps on, a right regular P.I.A but it worked, not too sure that the screws are not loctited in, If so  A soldering iron on the screw head works but as this is a rubber strap be careful it trying that method.

I've come across some watches from China with "fake" screws. If you inspect the screws carefully and notice that the cross is not deep enough to fit a Philips screwdriver in, it is most likely to be a fake screw. Nothing more than a case embellishment.

If that's the case and the strap has not hardened, you can try prying back the ends of the strap to see if a spring bar is hiding inside.

But as WW said, you can just remove the back without taking off the straps.

Thanks for the replies.

I cut away some of the silicone band thinking it would create the clearance to pull that cover up but, NOPE>

The silicone or rubber straps are so molded into the body of the watch there is son way to separate it.  I don't know what material it is but the straps is so damn strong I couldn't tear it with all my might.  And then the guts seem to be mounted to the back case from the front.  It's like they had the case and put it in a mold with the goop and baked the straps right into everything in layers.  It'd be great if it ran forever.

I don't think this was made to come apart and go back together.  But damn.  What a dumb design.  The battery dies and that's it?

Thanks for the intro @Berticus81 welcome to the WRT forum! I'm also relatively new and I'm in the middle of my first service of an Elgin Grade 313 movement which has been stalled for a while as I was waiting for oil and a mainspring winder. Well, my oil arrived today and luckily I picked up an identical 2nd movement so as I disassemble that one it will help me remember how to re-assemble the first one! I've posted some shots of my watches here.

Did you get the back off?

    • Den / Dennison is a unit measurement of size this is actually a mainspring gauge . I haven't heard of a pivot been measured in Dennison before.  Though the small thickness gauge is  usually supplied with a Jacot tool and is more accurately known as a pivot destroyer.
    • Could it be an abbreviation for Denier? "Denier (/ˈdɛniər/) or den (abbreviated D), a unit of measure for the linear mass density of fibers, is the mass in grams per 9,000 metres of the fiber. The denier is based on a natural reference: a single strand of silk is approximately one denier; a 9,000-metre strand of silk weighs about one gram." The pivot gauge looks interesting, however I wouldn't trust myself to drive a pivot into a wedge incase it jams and gets damaged/snaps trying to get it free. More a comment on my ability and incompetence than the quality or design of the tool 🤣
    • As I've seen multiple posts here about multiple types of cleaning solvents, I've done little more than confuse myself more thoroughly that I was before. To see if I understand things correctly... 1.  Is One dip is a solvent which is a cleaner and also a protective rinse for hairsprings jewels and pallet stones only? Or can it be used on all the parts (like the case and wheels and all the things) It seems like that would be much easier as it's just "one dip" but it is very expensive. 2. Isopropyl alcohol is a great cleaner for manual cleaning or ultrasonic cleaning (only enclosed jar) just not on pallet fork as it may loosen the shellac holding the stones. Does it have to be 99%? 3. When buying a small manual cleaning brushes, does anybody suggest a certain material of the brush itself?   
    • I am new to the new to the watch restoration hobby I have the basic tools. I'm here to learn new things. And utilize my resources (you guys) to expand my knowledge and hopefully save some derelict timepieces from the trash.
    • @Knebo It does make sense.   Most companies are trying to squeeze independents out.     Maybe I wasn't clear and complete. He said, the mid-case has been polished, he says it was probably to remove pitting. - It kind of makes sense to me, as the pitting on the caseback doesn't match the story of the mid-case. - The case is clearly overpolished and the lugs nicely brushed without any marks, so watchmakers are clearly polishing that area the question is how and how much. I am swarmed with work and will be visiting my watchmaker in a few days with the checklist and will post an update then. You have been really helpful. PS. Refer to the pictures in my latest comment for reference to this and the case at 9'o clock is actually sunk. the drawing is a bit hyperbolic.
