Luminox Resurrection
It all started with
a Luminox Navy Seal with a broken case, that I received as part of a trade deal.
I thought that a simple case swap would be really an easy way to fix the watch
up for use as a summer beater. Well, it turned out to be a bit more interesting
than I had anticipated. Makes for an interesting tale,
though.
First off, here's a
pic of the watch as I received it. The lugs were missing. Apparently the
original owner broke off one of the lugs (I have NO idea How!) and as such
trimmed the rest off, and was using it as a 'pocket watch" of sorts.

Step one.... Call
Luminox service department.
While
the folks there were extremely friendly and tried to be helpful, it turns out
that Luminox policy is not to sell parts other
than bands and clasps/buckles and replacement bezels, and prefer you
return the watch to them, even for those parts. They also wanted to see proof of
purchase (understandable) . After some conversation, I was told, "sorry, we will not sell you a
case, send the watch back, with $10.00 US for return shipping, and we will
provide you an estimate on repairs. If there is no adequate proof of purchase,
we reserve the right to refuse to do a repair" - I was told that
the average price for a repair similar to the one I wanted should be about $100.
So, $110 US to repair a watch I got for free? That's just about $150.CDN. I can
buy a beater up here for less. Still, its a nice watch,
so...
Step Two... Invoke
the Power of the Internet!
Posting
my story on several of the more well known watch sites came up with some
interesting stuff. I was offered the chance to get a new case through a
fellow who was a watchmaker. Turns out Luminox wouldn't sell him a case either,
it was again, "Send us the watch for service", although as he was a dealer, it
would have been a whole lot cheaper for me. Turns out there's some silly
rule about who can service a watch with the illumination system Luminox
uses. Still, there has to be a better way.
Enter the PMWF and
Shane de Laurian. Shane offered up a Luminox case that appeared to be the
answer..
Step Three .....
wait on Canada Post..
sigh...
Step Four ..... start the work..
This is where
it got very interesting. I started by looking at what Shane had sent, looked
pretty good, case was the same model (wait for it!), and only problems seemed to
be a chipped crystal, and no hour illumination in the chapter ring - no big deal
says I, I have those parts (hah!).. Let the surgery begin. I remove the
movement, and store it in a movement tin.
Shane's Case ready for the task at hand.

Step Five ....
Frankenwatch !
Round One...
Ever take a Luminox apart? Very interesting design. Turns out the bezel fits onto a steel
compression ring, which is tightly press fitted around the case lip that the
crystal sits in. This in effect, makes a very tight compression seal on the
crystal, which no doubt helps with water resistance. So, seeing as I need
the new crystal, I figure that I can remove it by simply popping it out from the
inside. Wrong! That compression rig really does hold it in with a death
grip! About a half hour later, the crystal and ring are off (and the case
is more destroyed than it was). OK, so far so good. Now to lift out the little
plastic hour chapter ring. Aghh, its in two parts, the chapter ring, and the
plastic part that sits under it and actually holds those really tiny little
glowing glass tubes, which as I discover, are really really tiny, and light.
Naturally, obeying the first law of physics of amateur watch making, these
little bits proceed to merrily fall from their plastic home, and land on the
carpet!.. ARGGH! Doom! Ruination! Quick, make sure the cats are NOT in the
room.. Some quick thinking suggests that if I TURN OUT THE LIGHTS, I might
be able to find them, thanks to that wonderful Luminox glow.
Sure enough, after a
few minutes on my knees with a pair of tweezers and some 4x
reading glasses I find them all (except for one second of panic after
having found 11 of them, and not being able to see #12), and safely corral them
in a 35MM film canister. A few minutes work with tweezers sees them back
in their proper home, and installed in the new case. Enough for now. The whole
project is safely stored in my favorite watch project box (actually a vintage tin cigarette
container, MacDonald's Export A, for those that care, and no, I don't smoke,)

Round
Two...
Time
to fit the crystal and compression ring. Crystal snaps in like a charm, but
the new compression ring is smaller than the one on the case Shane sent. Not
even close. To make it worse, when I try to use the one that came with
Shane's case, i discover that while it fits loosely, and holds the crystal,
the bezel, once on, condescendingly flops around looking rather smug at my
surprise.. Hmm, time to think. Back into the tin with the whole shebang,
and off to sit on the patio and be inspired by cold dark ale. (Big Rock
Traditional, for those interested in such things)

The Compression Ring from Hell
Round Three.....
Well, out
comes the heavy artillery, 1/4 inch fine finishing files and some really fine sanding
blocks.. I figure that with enough careful filing while rotating the case, I can
slim down the lip that the compression ring fits over. Hey, I used to have a
1940's Harley, I know how the brute force approach works!.
After two days
of very careful filing and sanding in short bursts of work so as to keep the
frustration level down, the compression ring looks like it will fit. In goes the
new crystal, and then the ring. Not quite. Now we start using the sanding
blocks, to fine tune the fit. Finally, it fits as it should. The crystal gets a
good cleaning in alcohol to remove fingerprints, and is inserted into the case
with light pressure, and a microfibre cloth (to avoid inside fingerprints.
Moment of truth. On goes the compression ring with help from a DIY crystal press
arrangement (i.e the whole affair is flipped
over on a mousepad, and severe pressure is applied via a hockey puck (
hey, this IS Canada, after all)). Voila!, the ring is in
place and seated as it should be. Out comes the movement from its
temporary
home, and in it goes, followed by the movement spacer ring, (which takes a
couple of tries to figure out which of the two that I have fits better). in goes
the gasket, and the case back is next. Four screws later, its down and
snug.
Now for the bezel. It fits,
but won't click. Hmm, looks like another slight difference between the two cases
is the problem. This is compounded by the wear on the plastic ring that has the
small stops the bezel clicks on. Off comes the bezel for a look see. (hey, I
must have got the fit right on the compression ring, it didn't come off with the
bezel ! Looks like I may never get the bezel to click stop properly, but by
slipping the left over gasket around the base of the compression ring, I not
only seal the small gap between bezel and case, but The bezel now has enough
resistance to turn smoothly, and stay where you leave it turned to. Close enough
for me. Off with the bezel again, and a little bit of silicone grease on the
gasket that's serving duty in the bezel resistance forces. One goes
the bezel one last time, and I'm done.
One
final hitch.. I go and dig through the big bag of watch bands only to
discover that the Luminox has a 22mm lug spacing. Time to find a nice 22mm
nylon or Nato type strap. What I ended up with was a "stealth" Timex
Expedition velcro fast-wrap. Why "Stealth"? Well, a permanent felt marked
blacks out the white "Timex" and Expedition Logo, as you can see...

I really like the way this turned out, nice beater and
comfy too. What next? I might put a Bill Yao sterile dial in it, and possibly
paint the tip of the second hand red. Another thing that would be interesting
would be to replace the green tritium glass on the second hand with a red one,
such as the one that is used to mark 12:00 on the hour chapter?
Ideas? Comments?
One more thing.. A great schwack of thanks to Shane, who
graciously offered up the replacement case. Thanks, my friend, couldn't have
done it without ya!
Cheers!
