Unknown watch movement logo. Very interesting

[FabioBastardo]

Does anyone know what the watch movement is on this old watch. No name on the dial just the word waterproof where a name should be. Interesting logo 

see photos

Reminds me of the Amida logo.

Whats important to me ...is who made the movement .

No it was ok Richard. When  clicked on the picture becomes clear.

Thank you. I was informed it was a cheap worthless Lack watch from India. It’s in a small mens watch looks to be around 1930 odd   Cleaned the movement and it’s going really well. Keeps good time. 
This is a great site. Mystery solved. I’m obliged.

Thanks very much. Do you think it’s a good movement. It’s in a very small wrist watch which is a mens the only thing written on it is Waterproof where the name would be 

[RichardHarris123]

Define good.  I think it's mid level movement,  not low quality.  Please post photos of the rest of the watch.

Be interesting to see who made it

Will do. Funny it doesn’t have a makers name.

‘Good’ is of course a relative term. The movement looks good for a wristwatch movement with a pin-pallet escapement. 

It has more jewels than most pin-pallet movements, and looks to have been built with serviceability in mind. 

Oris are the only brand I know of that made some more refined pin-pallet wristwatch movements, some of which earned chronometer certificates.

Here are the photos of the mystery watch. Grateful for any help with identifying it. Thanks everyone. Your knowledge is invaluable

Hi

i was wondering if you had looked at the photos of the watch. Do you know what it is. Obviously it’s very old. But as to the maker I have no clue 

thanks.

The logo is Sindaco SA. They weren't a movement maker, more of a put together of parts. The makers identity can be hidden in the keyless works parts.

Not always that simple. Typically the only reason we would have any way of identifying a watch is if parts were available at any time and somebody had a parts reference book then they would help you to identify the watches that they have parts or. Unfortunately there are hundreds of thousands of watch movements with no identification and of course typically no parts

the classic place were watches would be identified would be under the balance wheel and your pictures don't really show a good view of that. Occasionally I've seen watches marked under one of the plates. They felt very proud of their watch is a very prominent Swiss company and they ask he stamped the bottom of a plate so you have disassembled find it. Then there is the other system the keyless parts make up something called the fingerprint system but you still haven't given us enough information to make use of that.

Here's an image showing what a fingerprint system looks like. The PDF is based on the physical book the physical book has sizes of watches these are smaller ladies watches and keyless parts which in the physical book are printed at the actual size of the watch parts. So to identify with the keyless we need in your case diameter measured on the dial side and a good picture of the keyless parts and then you have to hope that this was made within the right time span of the books that have this system on the other hand a lot of times on the dial side they will also put markings.

So basically to identify a movement it has to come out of the case and has to be disassembled.
