1953 Hamilton Illinois Nautilus Model A

Hamilton purchased the Illinois Watch Company in the late 1920s - just in time for the Great Depression.  Illinois Watch Co. continued to make models for a few years but Hamilton eventually moved production to Lancaster PA and shuttered the Illinois factory.  

Illinois was a quality manufacturer though and had a very strong reputation.  Hamilton reintroduced the Illinois brand in 1953 as part of a strategy to introduce using Swiss-made ebauches without risking the reputation of Hamilton-branded time pieces.  

Europe was still recovering from the devastation of WWII and European watch companies made very high quality watches at price points that were difficult for US makers to compete with.  One by one, American watch companies either closed shop or chose a "if you can't lick 'em, join 'em" strategy of using Swiss-made calibers to lower their price points.

There were a few Illinois models introduced in 1953, including the first automatic models.  One of them was the manual winding Nautilus Model A.

In 1954 the Nautilus A was expanded to include different dial options and the bracelet was changed to what would appear to be a Kreisler bracelet.

 

1955 was the last year of Illinois branded models and the Nautilus A appears to had dropped the black dialed version.

I was recently sent a Nautilus A in need of TLC from a fellow collector.  At first blush it appears to be in good shape other than some radium-related corrosion on the dial and hands.

The back of the case appears to have been polished considerably but is otherwise unremarkable.

Inside the case is an Illinois branded movement based on an ETA 1080.  The TXD on the balance cock is the import code for Illinois watches.  All Illinois calibers with Swiss-made parts have TXD on the balance cock.  Hamilton branded calibers with imported movements have Hamilton's import code - HYL.

The 9514 inside the case back is the model number for this case.  There are no serial numbers for Illinois cases or movements.

The set bridge / set lever spring is broken and missing the detent section that engages the set lever.  You can see there's a piece missing where my tweezers are pointing.

The replacement part shows you what section is missing.  This odd-shaped lever holds the set lever in the winding or the time-setting position and is what you feel when the crown pops into position.

Everything is cleaned and dried.

The reassembled movement is bright and shiny now.  I think this may have been the first time this watch was cleaned as there were no marks inside the case back.

The immediate time keeping is a little low but that's easy to fix.

A tiny tweak to the regulator speeds the watch up nicely.

I relumed the hands and the dial.  Black dials are very challenging and I broke my cardinal rule and slightly cleaned the dial in an attempt to make it look better.  In doing so I lost a portion of the O in Incabloc.  I was lucky that was all that was lost - it just takes a moment to screw up a dial.  I cut my losses and the finished project looks pretty good with relumed hands and new crystal.  I could probably make the dial look better if I gave it a light spritz of lacquer but I decided to let sleeping dogs lie.

Overall this is still a great looking version of a fairly uncommon model.

1964 Mil-W-3818B DTU 2A/P (by Benrus)

You'll have to forgive this non-Hamilton post but I thought some folks might be interested.

Hamilton wasn't the only manufacturer to make military watches for the US (and other) military.  I'm definitely no expert on all-things military watch related but I do find the differences and similarities of various makers interesting.

One of the precursors to the  Mil-W-46374B and the GG-W-113 was the Mil-W-3818B made in the 1960s.  Military contracts were awarded then just like they are today - through competitive proposals that aligned with military specifications at the time.  Specifications defined the materials of construction, accuracy, luminescent requirements, durability, etc. and watch manufacturers would provide proposals to meet the requirements.  During WWII there were several awards for various wrist watches and in some cases different manufactures would even make parts for each other.

The Mil-W-3818B was made by Benrus and features their 17 jewel DR 2F2  caliber movement.  Unlike the Mil-W-46374B, the Mil-W-3818B was intended to be serviceable and is arguably more along the lines of the GG-W-113 in terms of quality.

I was recently sent a Mil-W-3818B for an overhaul, against my better judgement.  I really don't like working on non-Hamiltons, mainly because if something goes wrong I don't have access to spare parts like I do with most Hamilton calibers.  However, my arm was twisted and I was curious to see what would be the difference.

As received, it was in very-worn condition.  I removed the crystal and the crown before I decided to take photos for a blog post.  From this angle it looks like a Mil-W46374B

It took all of my strength to separate the two-piece stem.  In fact, I thought about just returning the watch unserviced - because I was afraid I'd break it.  But after checking photos of other examples online I decided to go for broke.

With the dial out of the way, this movement looks very ETA-like, and similar to many Hamilton movements.  It's a bit thicker, or more substantial though - but the design is very similar.

The back looks similar to a Hamilton too - like the 688 movement - but it has a three screw train bridge where Hamiltons only have two screws.  All of the screws on this movement are more substantial than a Hamilton caliber too.

With the balance cock removed you can see 2372 stamped.  There is no ETA symbol present but as I suspected, this movement is based on an ETA ebouche - just like Hamilton used at the time (and today as well).

The inside of the case back has no markings whatsoever.  I appear to be the first person to lay eyes on this movement in the past 60 years.

Disassembly, cleaning, and lubrication of this movement is just like every other ETA movement I've done.  I could probably do it in my sleep - but it still takes a bit of a delicate touch to get it all back together again.

The movement is ticking away with a good motion.  Without a crown, I haven't wound it fully but the watch timer will still give me an idea of performance.

Not too shabby... the amplitude is a little low but once it's fully wound it will come up to 230+.

The back of the case has all the markings one would look for in this model.  This watch dates to September 1964.  I added spring bars so a one-piece NATO strap will work.  Or a two-piece strap can be installed.

One of the specifications for this model is the second hand should have a luminous orange tip - so I relumed the second hand so it will glow again.  This actually turned out very nice but I think I'll still keep to Hamiltons, even though this is a very close cousin.

1953 Lindsay

 My blog has over 816 posts which makes me wonder how many unique models I've detailed.  A quick count shows I've documented 686 wrist watch models and another 34 pocket watch models.  There are about 1,000 unique wrist watch models and the ones that remain to be found are, obviously, more obscure, either rare, solid gold, or just way too expensive for my tastes.

I've posted on my project watch previous but this is a one year wonder, the 1953 Lindsay, so you don't see if very often.  It came in a 10K gold filled case and looks similar to several other models from the time.  Perhaps that was the reason it was only produced for a single year.  It was available on a leather strap or a metal bracelet.

Tucked inside the case is a 17 jewel 12/0 sized 752 movement.

As received, the project watch is in pretty good shape.  The crystal is a bit beat up but the case looks to be in great condition.

The case back is unengraved and exhibits little wear.

With the crystal out of the way you can see the dial is in very good shape.  The butler finish on the dial looks like it could be a refinished dial but I don't see the little notch on the side of the dial by the crown that is usually present when a dial is redone.

The 752 movement looks similar to a 770 movement.  All that's missing are 5 additional jewels and a shock protected balance.  Should this 752 ever fail, a 770 would be a suitable drop in replacement.

The inside of the case back is stamped with the model name.

With the dial removed from the movement, I can see numbers scratched on the back.  That's a clear sign that this dial was refinished.  Refinished dials on Hamilton watches is very common.  It was even done at the factory when a watch was sent to Lancaster for service.  Many people with "original dials" actually have old properly refinished dials.

A new glass cylinder crystal will make a huge improvement to the looks of this watch.

Everything is cleaned and ready to be reassembled.

Unlike my last project watch, this movement came together with no issues.  It's now ticking away with a nice motion.  Time to see what the timer thinks.

It's running a smidgen slow.  The amplitude of 201 is attributable to the fact that I haven't fully wound the mainspring.  

Fully wound with a slight tweak to the regulator, the beat rate is right where is needs to be.  I usually set a freshly serviced watch a little fast, as it will settle in.

With a new crystal and paired with a new genuine lizard strap, this Lindsay is looking fantastic and ready for some wrist time.
