Default 6309 caseback opener


Hi ,
today I received my new caseback opener from our fellow forum member Bry (bry 1975)

It's easy to handle and well made, a real improvement for little money.

Here you can see how it fits on my 6309-7040 Quartz-Hybrid:





highly recommended

I bought one too a few weeks ago and agree completely, it is very well made and fits perfectly. Very useful tool which fits the 6105 case back as well. Hopefully no more scratches on my case backs now!

Mark,


The non ferrous pins certainly wont gouge SS casebacks and from scratch tests don't appear to scratch SS case backs.

Hi, No-ferrous metals don't have a (Iron content) so they have no matterials in them that can effect marring or scratching metals.

Interesting post. I've been making do with a rubber ball type opener. It is certainly non scratching and versatile, but I doubt it can generate the torque of a conventional tool. I've only used it on old watches that were no longer in a factory tight screw down. Anyone used both?

I've been thinking about picking up one of those four a while, will that opener also work on SKX divers as well?

Hi,

The nickel silver 6 pinner SHOULD undo most SKX/6309/7002/6105 casebacks even really tight casebacks just be careful to hold the watch case and case tool steady.

I have this tool and the H558 case back opening tool, which also fits perfectly (I find) on the 7C43 crystal locking ring.
Both tools are great and never let me down, well recommended.

My turn to ask the question that has not been answered: How do forum noobs contact Bry1975 to enquire about this case back opening tool. Even us noobs hate scratching case backs with nasty wobbly adjustable case back openers that seem purposely designed to gouge case backs.

Hi Bry thanks for the contact. You still producing these openers? Looks like there's considerable interest an I was wondering when someone would figure out the secret to not scratching casebacksmight be using a softer non carbide holding medium for pins

Hi,

From previous experience most Jaxa type openers use cheap glass hard carbon steel pins, that gauge austenitic stainless steel like a knife through butter! :-) lol

Hey Bry, because the South African Post Office is in a complete shambles with recent industrial action and terminal systems problems I am still eagerly awaiting the case opener you made me. I've had to resort to other methods of getting parts and tools back and forth since.

I'll let you know as soon as I get it in hand and thanks for the effort you went to!

So far yes. Ive reverted to using DHL via Postnet. Private companies are more or less still OK, the state and parastatals are done for.

Default Re Case-back opener

I finally got my case-back opener as kindly made and supplied by bry1975. Apparently the latest is that the South African Post Office cannot afford to purchase the paper they need to print reciepts etc on so the parcels just sit.

Anyway the opener looks great. Thanks bry! very well designed and flawlessly executed build, solid easy to grasp with soft metal "claws" which only protrude about 5mm which should allow them to not bend as torque is applied to the tool. I haven't been able to try it yet as my watch is off travelling the world getting drilled lugs and a NE15B hacking movement installed.

That is a great looking tool. I got lucky using a rubber type ball that my wife had from her never watched Tae-Bo DVDs.

I know if I had seen this tool, I would have picked one up right away. I love people that come up with special tools. I know I have had to make a couple of special tools for working on my 65 MGB.

Anyway, great looking tool that I may have to add to my ever expanding collection of watch tools.

Ron
