    Here's the new one I was waiting for, I have received it today for $33. Why am writing all this, I have ran into a $20 quartz which was surprising difficult to open, so I've ordered the tool and my initial review here. There are various other similar pivoting ones available, form $15 all-plastic one, to the "King of the Orient", $100+ Seiko S-261.

    Sturdy construction. The reversible blade has two widths, 12 and 16mm, but the prying slot (where present) of some snap-back watches is like 5mm wide. That will be easy to correct, even if a replacement blade is relatively expensive for about $10.
    I think that in theory it could be improved. As it comes, the blade pries down, meaning that case hast to be put dial up and maybe one finger on top of it. Now, I'm sure that it will easily open 99.9% of snap-backs, and even remove stubborn bezels or similar feats, but I had liked it more if there was a way to hold down the case opposite side from the screw, and prying up.
    However the Chinese (or whatever Swiss maker it was copied from) may be right after all. Because in theory, theory and practice are the same thing, but in practice, they aren't.

    Therefore, see that you always have a magnetic strip around, to find the small pieces on the ground again.
    And don't forget them to demagnetize afterwords.

    Agree, opening a Rolex (with the correct die) is a must with this tool.

    Koen reacted to Mark in Smoothing versus cutting broaches: Do I need both?   
    Well, A cutting broach will, of course, make the hole larger and so if you wish the hand to still fit the pivot then smoothing broach is the way to go, depends on if you want to remove material or not  but be careful, even though they are smoothing broaches they may still bind in the hole as you turn and you run the risk of breaking the hand.
    To be fair, I have found smoothing broaches useful for clearing out stubborn debris. I remember finding what I suspect was glue in a seconds hand pipe once and couldn't use acetone due to the hand being painted.
    @rduckwor I have merged your "dual post" as it keeps the forum cleaner. Kindly be patient in waiting for other members to respond rather than opening new topics with the same subject matter - many people are on different time-zones - have jobs - or are simply spending time with family

    what would a "flat ground" look like?    it might make the tip too long and weak.   have you ever twisted the tip off a tight screw?  a compromise is hollow grind.  vin

    Well because with hollow screwdrivers, you have more grip the teacher say ( Omega service center ) and les chance to slip away or to damage screws...
    You don't want to damage movements, especially now with open case backs. But thats what we learn the first lesson, I am only the pianist. ;-)

    Yes, excessive battery usage is a sign of dried lubrication. Current draw can also be measure with analog multi-meter, to compare with manufacturer specifications. Many quartz modules are more practical and economical to replace than to service.

    This is x20 magnification. I can get up to x270 mag with an optional eye piece. X70 in current configuration which is great for looking at wheel teeth, jewels and hairsprings. Plus progressive linear zoom from x20 to x70. I love the well made piece of equipment.

    It works extremely well with movements that have seawater in them. Being a watchmaker not far from the seaside I used to get any amount of rusty watch movements to repair.

    Nice job man, don't thing I could do that!
    Your movies helped me a lot with my first 2 pocket watches, lucky they still worked before I take them apart and were compleet.
    The Hebdomas ( still not started with that one ) like you have is missing his bezel, but if I see how you make this small parts, it must be possible for someone to make a bezel to???

    Your confidence grows with each success. You should advertise in watch magazines. With your skills, you could make a lot of money. There are very few that have the skill you have. Loads of watch repairers, very few watchmakers.  Nice clear photos too.

    Hi guys,
    I buy a lot of old watchmaker's tools and yesterday I got another 15 kg worth of old treasures
    There's one that I don't recognize though. It looks like a brass plate and it has circles with numbers in them on both sides.
    Does any of you know what this is?

    I agree that Dumet isn't the cheapest. It's probably not really suitable for a non-professional watchmaker.
