    Question Tegimented 856 UTC Bracelet Sizing - Problem/Questions

    Hi Forum,

    I'm trying to size the bracelet on my brand new Sinn 856 UTC, I'm using the screwdriver provided with the watch (flat head screwdriver). While trying to remove one of the screws, the screwdriver's tip bent pretty easily, at the same time the bracelet's screw top got a bit stripped.


    - I have some questions:

    1) Is this situation common while sizing Sinn 856 bracelets that have the flat head screws (instead of thew hex screws)? has this happened to you?

    2) How much do you guys think a replacement bracelet screw would cost?

    3) What tool other than the one given with the watch (the small Sinn flat head screwdriver) should I use to to size the bracelet? I've been looking at this T screwdriver but it's kind of expensive.

    4) Have you guys used some trick to loosen the bracelet screws? the screws on my bracelet seem very. very tight.





    Thank you for any information!

    Take the band off an soak it in boiling water, or just boiled water. That will help loosen any Loctite on the screws.

    If no loctide is used (older bracelet): a drop of WD40 on the screws and than wait for one day. Maybe repeat that once....
    Heating it up may also work.....

    Yes its common, not only SINN-bracelets show that behaviour.

    The screwdriver is a pro tool. Very good quality. Price is high if you only use it once or twice....

    The screw is cheap, shipping will surely cost more.

    Order some replacement links and replace that one and the one either side. So remove the one either side in order to remove the damaged one. Just another option.

    I’ve had a lot of luck with the Wera screwdrivers. Make sure you order the correct size though.

    I found that using both the two solutions above worked for me. Dunk the bracelet in boiling water for a minute or two (preferably removed from the watch ). Dry it off and saturate it with WD-40 and leave it overnight. I don't think the Sinn-supplied screwdriver is the best quality, and I've found Bergeon to be reliable.

    I left the bracelet in boiling water for about 2 minutes, I then used the Bergeon 6899-AT-120 screwdriver (1.2mm red cap screwdriver)... worked like a charm! thank you guys for the suggestions!

    ....if you've got a real problem: here's what helped me.

    1) Heating it up may solve the loctide issue.
    2) Ultrasonic cleaner and WD40 do often remove rust: (repeat if necessary) WD40 1 day, ultrasoniic cleaner 10 Minutes until its open.

    If your a semi-pro with the right equipment: drill it out from the other side using first a very thin drill then a drill slightly thinner than the screw.

    If your a real pro: laser it out .

    NEVER, NEVER use the WD40-trick on 156 Military cases screws. Although it works most times perfect it may harm the dial. Here only the "real pro"-solution may help without the risk to harm/destroy your dial.
