First Model Concept

My understanding is that one is not allowed to say "waterproof" for fear of tort law... but we have our resident prosecutor / criminal defense attorney (@Aurelian) who I'm sure knows much better!  

I might deep dive into that. Always wondered about this. Thank you!

Nein zum Wasserdichten

The Federal Trade Commission banned the use of the term in 1960. It rescinded that regulation in 1999 when no one in the industry was using the term. No watch can be truly waterproof, not even that ugly bubble of a Rolex that was just released. Seems to be the convention to avoid the term.

Danke freund (I used google translation)

Updated (without the use of Google Translate).

Interesting, my oldest caravelle diver is from 1969, wonder if they were just testing if they could get away with "waterproof" on their dial in the late 1960s. The information is much appreciated friend!

It seems to be a gray area. Everyone agrees that the FTC did it and dates vary from 1960 to the late Sixties. The FTC did not control anything outside of the States, but the industry seemed to comply. 

I think those Caravels were using Citizen movements. Caravel let the barbarian inside the gate.

Yes, the divers were japanese sourced case and movements. Some models i think were assembled/source in what was west germany back then

Option 3 💪👌

You're having these COSC certified ? ( based on the "Chronometer Officially Certified" text on the dial)

Can I have just a bit of criticizm? Don't take it close to heart. I do it only of good intentions to help. It's about typography. The logo seems too big on a dial. Chronometer certified and water resistant are in different size of fonts and that looks weird. And because the logo is big and certified part is above the pinion it looks very cluttered on the top. I would recommend you choose a more unique font for text (it seems to be Arial - the most widely used font in the world). The number font is also weird. Almost looks like it is handmade, but the proportions are strange especially for a 3. 

The name also doesn't let me go the feeling that the watch is in the same land with Chinese Hrouland and Rundae. I know it is translated Dog watch, but if you don't know German it is the set of weirdly placed letters. I am very sorry. I don't want to be rude or offend you anyhow. I give very honest feedback that you can completely ignore if it is of no use for you.

I agree with @witcher.watcher about the fonts and the size of them. Will depend on the price but maybe the officially certified won't be necessary. Sometimes less is more, and in a dial this is important. I have other comments I'd like to highlight. 

Are you going to have the hands lumed?

I like the shape of those hands but for a diver might be difficult to distinguish in low light. A baton minute hand and an arrow or shovel  hour hand and both with lume could do the trick. There are some Caravelle Seahunters with shovel hands that look the part.

Version three is my favorite but would add markers to the minutes in the bezel. That is part of the charm of the Caravelle.

I see it's a countdown bezel. That is awesome by the way.

About the Hunduhr I'd make it a bit smaller and thinner. That would make it very classy. Do you plan to have the lugs drilled?

Thanks!

You know Hunduhr means Dog Watch in german?

You might want to put lume on your watch hands. Kinda odd of a diver without the lumed hand, you know?

Also, the fact that these are two nouns combined without any noun declension might appear a bit generic to a German. But I don't think anybody else would care.

Exactly what I was going to write. 
 

Also, I am a native German and find the name a bit odd. 
Odd names don’t necessarily have to be a bad thing, though. 
 

Its hard to see, but the concept hands do have a strip of lume on it. The final dauphine hamds will definitely have lume
