Ok ive scoured the web as much as I possibly could and I cant figure out, what seems to me, to be a pertinent question.
I see i can buy Seitz sized jewels from the supply house. So I'm assuming that the jewel press by Seitz/bergeon has reamers with OD's that correspond to their jewel OD'S. much like the bergeon bushing tool has reamers that match the bergeon bushings.
They also still manufacture K&D bushings for a K&D bushing tool (or as i have it set up, my bergeon bushing tool using K&D reamers made to fit my bergeon).
This leads me to my question of anyone who knows/uses the K&D inverto 18R. This staking set is also a jewel press, yes? And the reamers accompanying the staking set i would assume to be reamers for jewel insertion. Are the K&D reamers obsolete? Or is there some standard for jewel OD'S?
I need to purchase a jewel pressing machine but i also wish to upgrade my staking set. And it appears that Inverto 18R would kill two birds but only if i can find jewels to match the reamers.
Am I making sense with my questions and info?
Hi I have attached the tech sheets for the tissot models as there seems to be a lot of parts which are common across the range. The balance complete is 720 without spring and 721 with spring attached, so by the fact it is supplied as a spare it is detachable. the spring its self does not look too bad and most probably be re curved ok. If you could supply a picture of the balance and cock laid upside down so members can see the attachment it would be a great help. cheers
