Default Help me help you...

...one of my favorite rants by Dr. Perry Cox on Scrubs. But I digress...

I've been having a time of it obtaining a single set of pin and collar for a particular Seiko bracelet. NOSERV is little help and wants $2.95 for each pin and $2.95 for each collar, plus postage. AND they give no consideration for someone in the trade. BS, as usual, from them.

I've finally located a supplier who has these parts at reasonable (but still full retail) cost.

My issue is size. And nowhere does size matter more than with these very important connecting pieces.

So, I call on all of you to help construct a consensus of the various pin diameters used in Seiko's bracelets.

Please help by getting accurate pin diameters to me. They should be 0.90mm, 0.95mm and 1.10mm but let's see what you come up with.

My goal is to make available packets of two or three sets for those of us who lose them as well as packets of two or three collars only to replace those that evaporate before our eyes while working on these bracelets.

Get your calipers up, boys. We're going in.

If I knew the answer to this WIS mystery, I would be a very wealthy man. )

Wish I could help, but I do not have a reliable caliper.. I can only get approximate sizes.. ( It's a plastic caliper from Vonder )




About the mystery of the vanishing parts... that's a b**** alright! not even scanning with a magnet I'm able to find some pieces that suddenly *poof*




Good luck!

So basically you want us to measure the pin diameter and collar diameter for the bracelets of the watches that have them. For example, we should return a form to you that reads something like this:
  • Brand: ________
    Model/Nickname: ________
    Bracelet pin diameter: ________
    Collar diameter: ________
Does that sound about right?

Here's one :
Seiko Arctura Kinetic
5M62-OALO
Pin dia. = 1.20 mm
Pin Length = 19.0 mm
I'd offer measurements for other watches, but the pins are lost )

I don't have any measurements to add, as my digital calipers are crappy and basically unreliable, but I think this is a great idea.

I'm going on three years in this hobby, and I still find a way to lose a pin and collar every so often. :-[

Lol I don't have a caliper but I got plenty of "evaporation" over time. I always work in my office and there must be a least 4 or 5 collar and 2 or 3 pins lost. Must me the dog...

I'm not counting the spring pins.
Great Idea Jonathan!

The dog denies everything

Thanks for the input so far, guys.

I believe the pin diameter is the critical dimension as the length can be altered if need be. The collars will, of course, correspond to their pins.

Even approximates are good as I'm trying to get a feel for the sizes being used by Seiko.

Perhaps a kit of three sizes, two pins of each and twelve collars, four of each.

I love the tales of "evaporation", too. Especially since I lost a very rare crown about an hour ago to the "black hole" in my office.

In any case, please keep the input coming.

Yes, Andrew, measured this way (with a digital caliper):



It doesn't matter so much which model the pins come from as it does to determine the diameters of the various pins. When I spoke with NOSERV, no one could give me this information but they did say there were "a few different sizes".

Cheers,
One of my best (before i developed my fool proof method) was a click spring from a Bell matic that went into orbit, I looked for some time but due to there size and the orbits they can reach I had no chance and gave up, later on before going bed I went to clean my teeth in the bathroom and whilest looking in the mirror i saw a "speck" on my nose, yes you have guessed it was the click spring !!! )
