Le-Coultre Futurematic

Recommended Posts

I have a love of bumper automatics, and have a few from different manufacturers in my collection. The Holy Grail that has eluded me for a long time is the Le Coultre Futurematic. This has now been put right by my latest acquisition from Germany.

This Futurematic has a complicated, but very well made calibre 497 movement and is keeping excellent time, about +3 seconds a day on the wrist. It also produced a nice clean graph with no beat error on my Timegrapher. I will service it sometime in the future and post an article about it. The only thing I have done to it is re-finish the original crystal and give the slightly worn gold finish a light polish and fit a new strap. I'll do a proper job later when I service it.

Unusual features are:-

The watch has no visible crown, it is hidden on the back of the case in the form of a flat serrated button. To set the watch, slide the button towards the middle of the watch then rotate it to set the time. There is a built in hacking lever so it is possible to set the time to the exact second.

The watch cannot be wound by the button, just set the time give the watch a couple of shakes and wear it.

Manual type mainspring that has no facility to let it slip when fully wound like other automatic watches. When fully wound, a latch comes into play and locks the bumper rotor preventing it from moving. When the spring unwinds slightly, the latch releases and allows the rotor to swing again. The good thing about this system is the rotor only moves when required and cuts down on bearing wear.

Another strange feature of the spring setup is it is pre-tensioned with one and half turns of preload when run down. This ensures an immediate start up as soon as the rotor moves, negating the need to give the watch a good shake before wearing it.

There is a power reserve indicator at the three o’clock position on the dial that rotates clockwise when winding. When fully wound, the indicator just touches the bottom of the gold quadrant, and when run down, the hand is in the vertical position at the beginning of the red quadrant. Power reserve is 27 hours.

Just as an aside, when re-casing the movement the matt black dial was a sod to clean properly. After using the puffer I noticed that there were still some tiny specks on the surface. They are easily removed with the lightest touch of the Jewel Picker Upper!

I hope you found this interesting.

Great looking movement   from the photo the hairspring looks strange?   is it just the angle?   Just wondering I have not serviced that particular JL movement yet

 

Sincerely,

Jim

I see what you mean Jim. It is probably is just an aberration due to the lens and the angle the photo was taken. The watch starts easily and is holding excellent time, so I don't think anything is amiss. When I strip I get around to servicing it, I'll have a closer look.

    • Thank you for this post. Adding on to it, I've done a little digging trying to get the most bang for my buck. So I really wanted a set that had a base. You can buy the screwdrivers for around $33 usd 10 Piece Screwdriver Set. The base is around $32 usd Rotating Screwdriver Base (Grey) plus $20 in shipping, with tax you are looking at about $90 which is an excellent deal for what you get but I still didn't want to spend that much. I saw that they had the 9 piece set w/ base for $59 usd 9 Piece Screwdriver Set W/Base and I had a 'welcome discount' and got a matching 3mm screwdriver for 99 cents. 3mm Screwdriver. (without the discount the screwdriver is $6) With free shipping my total was $66.55 usd. So, I saved about $24 to go without a slot for a 3mm screwdriver. I'll take that! I hope this helps anyone looking to save a buck or two. Also, this corrects the issue of the orange 1.8mm screwdriver. 😉
    • No hex wrench needed there. Screw driver in case of AS1475 or just push the poinst down in case of Poljot2612.
    • Well, what is written here can't be explained with the wear of the winding/sliding pinion. Probably it is some kind of delusion from You side. But it prevented the people from pointing the reason of what is happening. Otherwice, this kind of wear is one of the common problems of winding works in watch movements. It meets often in old or cheap movements, or particulary in negative stem system pocket movements where not proper adjustment of the sleeve that guides the stem is done.  
    • Well I started with the rotor, then I couldn’t find how to let down the power so I removed the balance then found the click and let down the power.  After that I took apart most of the watchmaker side with the exception of the hour wheel which was still held by the cannon pinion and the hour wheel bridge which I put back when I realized the above.  I then went to the dial side and removed the cover plate. There were a few flat part which I had no idea what they were or where they should go as they got stuck to the plate by lubrication. Luckily I found an assembly video of that movement by the watch smith and he explained that those parts are part of the quick date setting system.  So I put them back in place and took a picture before continuing the disassembly  One thing I keep hearing in video or seeing in forums is that Chinese movements are often not lubricated. WellI can tell you the one I have is drenched in oil. Everything is stuck by capillary action on the dial side and I see pools of oil under each wheel.  Quite a bit of lint stuck to the oil too Just realized there were 3 screws, 2 holding the yoke maintaining plate and 1 holding the setting lever jumper.  I hope they are the same because I mixed them up and I can’t tell them apart.    Done with the disassembly and done for the day. For the reassembly I have a video to follow which is great because the dial side is quite complicated and I couldn’t take good pictures of the components position as several got stuck on the plate by lubricants as I lifted it so I never saw where they were supposed to be. 
    • I have one, but I don’t have the hex wrench to remove the stems. Does anyone know where I could get these in USA? Thanks in advance for any advice kind people!
