Some years back, I purchased a gently used Citizen Eco-Drive divers type watch. Good to 300 meters depth.
It was equipped with a black polymer/rubber watch band. The watch band was Citizen OEM manufacture.
The watch was in the neighborhood of $300 new, and the watch seller on another Forum was asking $75 for it.
My "spidey" senses should have kicked in, but didn't.
I suspect, and can't prove, but now I believe that the seller had figured out his watch was a "Weird Alice" model
that no longer had any Citizen Factory support. So he dumped it, and I was the more than willing sucker.
This past November while out deer hunting, I felt the watch band suddenly lose tension on my wrist.
I reached inside my coat sleeve and pulled out the watch, the band had broken.
I went to the local jeweler, who happens to be a Citizen watch dealer.
That beautiful Citizen Eco-Drive divers type watch is now discontinued.
The special ***proprietary*** polymer/rubber watch band for the discontinued watch is also discontinued and unavailable anywhere. So basically, an unusable watch. Darn, I wasted the $75 and I now felt like an fool.
So this watch is a one-of-a kind-case lug spacing of (0.551") which is 14 mm. Also a special one-of-a-kind shape/profile near the rounded portion of the watch case. The Factory watch band continued past the watch band mounting pins and went right up to the rotating bezel, filling in the "gap" for visual aesthetics.
I removed the two segments of the broken watch band.
I ordered a cheap Amazon 14 mm width fabric watch band and installed it.
NO, I am not going to wear that combination outside the house! Way too feminine!
I eventually gathered the emotional fortitude and figured out how to hold the Citizen Eco-Drive watch in my non-angle Kurt milling machine vise. (duct tape on the hardened steel smooth vise jaws, for additional traction)
I then proceeded to mill the spacing on the watch case lugs out to (0.866") which is 22 mm using my Bridgeport milling machine, and the 22 mm watch band width is manly enough for me.
I do have a angle vise for my Bridgeport milling machine, but being about 35 F degrees out in my shop building on the day I did the deed, so it was hurry up and get it done! I did the watch case modification with the standard vise. I would have been able to do a slightly nicer job using the angle vise. For you machinists, I used a resharpened 3/16" carbide end mill.
I milled about 0.1575" from the inside surface of the four watch case lugs. Not easy to do as the round watch case surface gains "altitude" and is in the way of the small end mill.
All in all, I'm reasonably happy the way it turned out. The way it was, the watch was virtually unusable.
You have to look pretty carefully now to see the watch case lugs machining when the watch is strapped on your wrist. The machining on the opposite side from pictured turned out more symmetrical. All freehand, and using the Bridgeport graduated dials.
That Citizen Eco-Drive watch will now accept any 22 mm width watch band. Rubber, leather, fabric, or stainless steel.
My local jeweler had the 22 mm width stainless steel watch band in stock, for about $33 and change.
The jeweler was "shocked" at what I had done.
He said he now had an unbeatable "story" to tell at his next watch/jewelry convention!
When spring arrives, I'm planning on using some rubberized "Cratex" abrasive wheels on a Dremel on the newly machined surfaces on the watch case/lugs. Essentially some light polishing.
