WWII Naval Aviators Watch model 39108

Arguably my beloved genre of Hamilton watches are the armed forces examples from WWII. There are a lot of distinctive designs and Hamilton even created watches for allies of the United States. Hamilton created pocket watches, wrist watches, chronographs, chronometers, elapsed time clocks, you title it.

Some of the toughest to obtain (or high-priced) models to uncover are the kinds built for Canada and Russia. You may see them arrive up for sale from time to time even though. The most ubiquitous versions are the Ord Dept watches made for the US Military, present as the Hearth Command Wrist Observe underneath.

As a Navy veteran I specifically like the styles created for the US Navy, either for the Bureau of Ships (BUSHIPS) or the watches for naval aviators, possibly in the Maritime Corps or the US Navy.

I am not positive what section selection 39054 is but I suspect it is the very same as my project watch for this submit. It is recognised as portion quantity 39108 under the R88-W-800 deal.

In most circumstances (pardon the pun) you will come across the same movements that Hamilton utilised in civilian watches. There are some exceptions the place modifications ended up designed to satisfy distinctive military needs. A fantastic case in point is the 2987 motion with 18 jewels. It’s fundamentally the similar as, or quite comparable to, the 17 jewel 987S other than it has an 18th jewel to guidance the 2nd hand pinion.

My job check out arrived courtesy of the primary owner’s son. The unique operator flew PBYs with the Navy and I would wager that he in all probability knew my wife’s maternal grandfather, who was navigator on PBYs in the Pacific.

As been given, the observe appears to be perfectly used but also very well cared for. The crown has been worn as a result of the chrome and perfectly into the brass. The crystal is so cloudy that most of the specifics are shed to haze.

The again of the check out is also well-worn. The scenario back again is stainless metal but the case is chrome plated brass. It can be not uncommon to see a whole lot of dress in to the edges of the situation when the scenario back again is nonetheless audio.

Hamilton army watches applied circumstances by Wadsworth, Star and Keystone circumstance makers. The 39108 utilizes a scenario produced by Keystone. The KH3 on the outside the house of the scenario back again indicates Keystone and the inside of the case back again is even a lot more plainly marked.

Guiding the circumstance back again is a dust protect that pops on to the motion ring that secures the motion to the inside of of the circumstance. Encompassing the dust address is a gasket to assistance preserve the view water-limited. You will find also a gasket in the stem tube – although all those are usually no extended secure immediately after 80 decades.

The 39108 employs a 987S motion. This caliber is extremely related to the 987A with the addition of a huge sweep wheel on the 3rd wheel and a compact seconds pinion that goes via the center wheel. The pinion is held by a keeper secured with two screws as revealed below.

With the cloudy crystal out of the way you can see the information of the dial. This dial is first as you can clearly see by the Hamilton brand name on the dial. This engraving would very likely be shed if the dial was refinished.

Observe also the hour and moment fingers are stainless steel. This is a significant element to look for with a US Navy look at. The watches for the Marine Corps would have a white dial, as shown in the catalog facts higher than. The arms would be the classic blued metal.

You are effectively-suggested to use a exclusive lifter to take away the massive sweep wheel. It has differing ends that let you to interact the wheel at the center and raise it straight off the pinion. You really don’t want to problems the extensive pinion on the 3rd wheel or your next hand would not get the job done the right way.

As you can see, the sweep wheel has 5 spokes so one particular conclusion of the lifter straddles a spoke though the other engages a distinct section of the wheel.

The really hard part is now out of the way. Following I am going to take out one of the two screws retaining the sweep pinion in put and move the keeper out of the way so I can lift the pinion out.

The 987S was Hamilton’s initial hacking wrist look at movement. That indicates there is a small mechanism that will end the view by gently partaking the stability when you pull the crown out to established the time. You can see the J-shaped spring that will “hack” the view.

The mainspring within the barrel is an previous blue steel example. Whilst it is nevertheless well lubricated, I might wager it has set in place and shed most of it’s probable strength.

Yup – named it. I’ll substitute it with a contemporary white alloy “lifetime” spring.

My ultrasonic cleaner shook a screw unfastened from the equilibrium. These timing screws are little. With no this screw hooked up the stability would tick wicked speedy. I want to put it back in it is really correct place to continue to keep the stability poised. Can you notify in which it should go?

To tackle little screws like this you definitely need a little pin vise. A pin vise retains the screw so you can get it commenced and then you can tighten it with a screwdriver. The screws in the harmony are symmetrical with the equilibrium arm, so I know the lacking screw goes upcoming to the balance arm in the open location.

Ok, every thing is cleaned and completely ready to get set again alongside one another. It is really all significantly shinier now that it’s been by way of the ultrasonic for 20 minutes.

The balance is reinstalled and the enjoy is now ticking away with a good movement. I will place it on the timer prior to I reinstall the sweep wheel areas. That way I know if you can find an concern with them. At this place the movement appears to be like like a garden wide variety 987A.
