Weird movement. Does not look like the typical, high grade A.Lange&s. one...

 

[city-dweller]

the last one is described by Knirim as belonging to a batch which was shipped to the Artillery School in Glau (this is in Brandenburg, not far from Berlin)

one of the important requirements (apart from the mirrored numerals) was a luminous second hand jumping every 1/5 s --
hence apparently the huge size, otherwise it would be difficult to resolve that small time intervals.
and, according to the order, it had to have a wrist strap.
(details are given in the description visible on the last photo)

difficult to imagine how one could wear such a beast and not bump it into something around...

5 x 60 x 60 = 18 000 bph movement.

Another "adjustment" ... Dial/seconds hand.

Here is the Lange dial on a Laco case. I really like this one, but would we go for a vintage look and could that be created?

I'm going to see if I can move some files over and do a few more tomorrow. Janne already got the SS so I'll do the torpedo and a marine as well.

Re: Marine Theme

Is the Longines here really a marine theme? It seems very similar to the Weems:

The vintage longines shown is the famous Lindbergh hour angle watch, not a marine.

Longines still producing watches based on this design time to time, in various case sizes
and materials. So we have a possibility to pick one in new or secondhand under Longines's own brand name.

I do not have enough knowledge to elaborate on Captain Weems and Lindberg but I'm sure they are master and pupil and Lindbergh later advanced the idea of Weems watch on his own hour angle watch.

Re: Marine Theme

The fact that the W-SS watch has been already redone by aristo removes the uniqueness we want to achieve with this Special Project, IMO.

The more I think about it, the more I'm thinking this myself.

Torpedo Theme

This file for this dial was pretty low res so it turned out kinda blurry.

Not-really Marine Theme

Re: Not-really Marine Theme

How would they look like with the 44mm Marine case?

 

[vipereaper30]

Re: Not-really Marine Theme

The Longines design looks like it would be a perfect fit, maybe for the torpedo too. My guess for the arty and Lange that the flieger is the better choice.

I'm a fan of the larger cases. If we really only have 3 options then the 44 might end up being the best compromise.

Re: Torpedo Theme

Here is the image with a higher resolution (Knirim, p.252)
(can make at higher resolution, if required).

According to Knirim's description, this is not a torpedo timer,
but rather an anti-submarine depth charge timer.
It was made by Junghans using cal. 29c.
The dial has a 1/100 min scale and three concentric scales
for distance determination plus one additional small subdial.
Further details on its use are seemingly unknown.

(There existed an identical design with a white dial,
but all scales and numbers printed in black (Knirim, p. 253) --
sorry, I didn't take a photo of it.)

Personally I cannot see how this beautiful device
can be transformed into a sensible writst watch...

 

[city-dweller]

Here is, in my opinion, an interesting design (Knirim, p. 222)
which can be rather easily converted to the special project watch
by removing the subdials:

This is a Navy B-Uhr made by Lange (cal. 48.1).
The subdials are power reserve and small seconds.
An interesting feature which I didn't see anywhere else,
is the the presence of two -- large and small -- second hands.
The large one was apparently to make timing easier.
(Unfortunately, no further details are given by Knirim.)

I like the hands very much.|> Widest points on the hour hand is rather close to dial center and the lume on minute hand is long enough. What is more, both hand's dial center side end is pointed. I don't like the hands which LACO is currently offering on 42mm and 45mm A dial.

As this interesting example is Lange, not LACO, I would rather see these hands on LACO's A dial(of course second hand should be LACO's counter weight end).

We see really a lot of B-Uhr A dial in the market, but for me, non of them are perfect with regard to hand's proportion.

An ultimate B-Uhr A dial would be a good theme for this project IMO.

I just found an excellent example on Chrono24.

Re: Torpedo Theme

There are three ways I can think of that you could easily use this design as the basis for a watch. Others will no doubt have better ideas, but here are mine to start the conversation. I fully recognize from the start that any design based on this dial will be a loose interpretation. Since this is a stopwatch and we are converting it to a different use. But I love the creativity and originality of this.
1) (This is my favorite) A single handed watch design with an outer blue ring representing the 24-hour day and perhaps the sub dial for power reserve.
2) A standard three handed dial watch functioning much the same way a B-Uhr B dial does with the hours on the inner red dial and the minutes on the outer blue. And if possible the sub dial retained for power reserve.
3) A three handed watch with a stopwatch function, not sure if the Durowe movement has this capability.
None of these designs will be exactly related to their stopwatch parent, but all would be inspired thereby.

One way of adopting the dial would be to assign one function to each scale ( one for the hour hand, one for minute and one for seconds)
Change the writing on the scales. Maybe just pips for the seconds.
Then change the text on the non functional scale to (maybe) WUS Laco Special Project 2011 or whatever.

There is another stopwatch design in Knirims book, I think I have a small pic early in this thread.

Any chance of a better pic?

This is a Zenith Deck watch(photo left). Colored hands and matching scales like this would be an idea for adpoting stopwatch designs into a wristwatch.

Just replacing bold decimal index on Zenith with deciaml and green "Annaeherung" index from stopwatch will work, IMO.
