    New and Old Technology together

    Hello to all readers of the forum. In this topic I would like to introduce you to some manufacturing techniques, unfortunately, still not widely used.
    They concern a modern technique (laser welding) coupled to an older (Lapping Grinder machine). The welding is used to add material in bruises, in the most
    deep scratches and in the parts ruined by polishers that usually are not accompanied by appropriate equipment. The excess weld (stainless steel on stainless steel,
    18k gold, 18k gold and titanium of titanium) is then removed to bring the case to the original forms. These are some examples of what can be achieved
    with these techniques. Greetings to all friends of the forum and sorry for our english...

    Outstanding, thanks for posting this! So can you tell us more about this -- is it something you or your company do? And I would guess that it is expensive? Hopefully, not many watch collectors will experience this type of abuse that needs an extensive restoration such as this, but you never know!

    Heard of laser weld technique. I also heard Lange does this if polish is requested when it goes in for service (thus apparently, they specify that UNLIMITED # of polishings can be done).

    I wonder how much would this be. I COULD have used this technique earlier.

    Is there anyone in US that does this? ( I THINK there was a Jeweller which advertised this service)

    Thanks.

    Re: New and Old Technology together

    That's really quite remarkable, thanks for sharing. I'm wondering though (not being a machinist) how the original case shape/dimension is captured in the process of removing the weld excess and finishing?

    Cheers,

    is it something you or your company do? And I would guess that it is expensive? Hopefully, not many watch collectors will experience this type of abuse that needs an extensive restoration such as this, but you never know
    For our personal experience the cost of repairs is not excessive for 4 reasons:
    1-The estimates we are accepted by collectors for 95%
    2-After the restoration of the watch value increases and this increase pays for the cost of restoration.
    3-With this technique you can solve problems such as severe corrosion of the casing (that if not blocked is destined to increase in years)
    4-The case takes the original geometry that polishing unprofessional ruined.

    how the original case shape/dimension is captured in the process of removing the weld excess and finishing?
    The process of removing the weld excess is done with lapping machine. We don't use the " polishing machine" that using felt and cotton brushes deforming and rounding the case and the planes
