Hi guys,

This Ploprof 600 is on my radar.
What can you say about it in terms I should be concerned about?

I think I can see the following:

MK I case
B1 bezel
Tritium D4 dial and hands

So if these observations would be correct, could I assume the watch to be from around -72, with a correct bezel, hands and case, but have a -76’ish meter/feet dial replaced?

Are my observations correct?

What’s your opinions on the state and condition just from these pictures?

I just want to make sure i’m not biting the bitter end of the apple.

It doesn’t have a EOA, so what should a man do?

 

@JanV I can't really help you the observations, I would check omegaploprof.com if you haven't already.

In terms of general condition it is very attractive in my opinion. Nice case finish (looks like there is some case to spare below the bezel?), no major scuffs or cracks in the bezel and tritium dial and hands. Do you know if the shark mesh is the original one?

 

Hi,

I’ve been scouring the OF for all Proplof info already.
There’s a lot of info, but not so much on the dials, from what years the different versions where made and available.

I’m trying to get a hold on the serial number also.

 

It certainly has an attractive dial, hands, bezel and case but as roryoc11 has said check out omegaploprof.com .
An EOA would be a good idea if you’re paying a full price since so many of these have swapped out movements.
The 166.077 are great watches!

 

I would expect that watch to be all original, and date to about 1974-78 when the extract comes back. The mesh looks like a modern service replacement, easily identifiable by either a circle with 37 for the original or 59 for the modern service item. The red button looks original which is nice, can't see the crown but I would guess it's also original.

The main worry is it has never been serviced and the rubber seal on the dial has degraded to oil. It is hard to see in these pictures, if it has there is some risk of contaminating the dial when servicing.

 

as @Dash1 said, it looks good so far but the most important is movement serial and extract.

 

Thanks for your thoughts. Will chase for a serial, but I know there is now extract ordered for the watch yet. So that would mean 3 months of waiting....

Are your sharing my opinions, that this watch has a Mark I case and hands, B1 bezel but a later D4 dial, and that this might have been exchanged in a service?

Or could the watch have been delivered originally with this dial? Or that this watch has a wrong bezel or wrong case?

 

Thanks for all the help and input so far!
The bracelet is the modern 59 model. The watch has been serviced and tomorrow I will get the serial number. The fact checking continues.....

 

An anyone tell me the main differences between a MK I and a MK III? (dial, bezel, hands, etc). The Proplof website doesn’t explain this in a clear detailed way. Just wanting to get more knowledge about all different iterations out there.

 

all u need is on the website

the MK is related to the dial ....

 

I’m still a bit confused on the MK differentiation’s.

If I’m reading the site correctly I can identify:
1. two cases, MK I and MK II.
2. two different bezels, MK I and MK II.
3. five dials that could be divided into MK I, II and III.
4. four different hands that I can’t separate into any category.

I’m not calculating in any prototype or service parts.

So what (so I can understand correctly), MK category is this Ploprof from the Omega catalogue in -74 belong to?

I see in the ad a MK I case, a MK I bezel and a MK III dial.
So is the MK I bezel doing a “comeback” with the MK III dial, or is only the dials that sets the MK category for all iterations? And the bezels can be whatever versions in between?

Just want to understand this better, as I now bought the watch above.

Grateful for all help and directions to bring me to the right path of thinking.

 

u make it more complex than it is .... i repeat again the MK is defined by the dial ... as long u don't know the serial it is useless guessing anyway as this is the delivery is the info which tells u what should be mounted

 

Here are some more shots of the watch, I bought it and instantly fell in love with the dark blue dial and the lume when I saw it in real life.

 

Wow, beautiful watch!!

 

That is a stunning dial!

 

A beauty. Did you get the serial number? I would be interested to see where it lies.

 

I’m hunting it down as we speak.
Busy travelling, so no time to do it before.

Will return when I have it.

 

My guess is 33,14x,xxx dating to 1978/79 I will be interested to see if I am close!

 

One question, So as this is clearly a darker blue dial, should this be considered as COMEX dial, even though it’s a MK III?

 

It is an interesting dial. I have never seen a ft/m dial that dark. Usually it is only evident in the sandwich 600 dials. It points towards ageing or rather a reaction to atmospheric conditions being the reason for dark/black dials.

Aesthetically it is very pleasing.
