Omega Seamaster 1000m “Grand” Ref. 166.093 - final observations before listing

Jozef · Jan 21, 2026

Following up on an earlier discussion I started here in December regarding this Seamaster 1000m, I wanted to share updated photographs and invite any final observations before listing.

This Seamaster 1000m “Grand” (ref. 166.093) was purchased new in Australia and has remained within the same family since. It has seen little use in recent years and has been left untouched, including no case opening.

I’ve included a detailed set of photographs and would welcome any comments regarding originality, configuration, or points worth noting prior to listing. I’m happy to clarify or provide additional information if helpful.

Many thanks to those familiar with the model for taking a look.

Photos below show the dial, case profiles, bezel detail, crown side, and bracelet clasp, and exterior caseback.

I have had a couple of Ploprof 600's but I've never a 1000. If you are looking for comments before listing for sale then I'll just say be realistic with your valuation.

Although it may be in your view in original state that does not mean that it is in an attractive or valuable state. To my eyes it is unattractive as it has a heavily worn dial with darkened lume, hands that look like they have been painted white at some point and a case that is also quite battered looking.

These are watches with quite a niche market, hardly a spur of the moment buy for a collector and I feel that in this condition it would be a hard sell unless offered cheap.

Thanks for taking the time to share your perspective - appreciated.

Condition and aesthetics are of course subjective, and I understand this style and level of wear won’t appeal to everyone. My intent here was simply to present the watch transparently, in its untouched state, and invite observations ahead of listing.

I appreciate you weighing in.

The case doesn't look too bad, but the crown seems to have talken a hit? The crown tube looks bent.
The dial is pretty sorry looking and the hands are of course painted. The dial alone would put me in off

The watch has not been opened and remains as acquired from the original family, so any wear or aging reflects long-term use rather than restoration. The crown and tube function correctly; the appearance may be accentuated by macro angles, but I’m happy to provide additional photos if helpful.

As with many Grands, dial and lume condition are very much a matter of personal preference. I’ve tried to present the watch transparently and welcome differing views.
Thanks again for looking

Beau model il est vrai.

Beautiful watch! I have the “little brother”, the Omega 166.091.

The original 166.093 is a lefty.

Thanks, you’re right that most 166.093 ‘Le Grand’ are left-crown. Mine is a destro/right-crown configuration, which is uncommon but documented on a few examples.

A watchmaker probably took it apart and put it back together upside down.

Jozef · Jan 28, 2026

Could be - but please check OmegaSeamaster1000.com for the history and assembly details of the Seamaster 1000 cases.

The idea that this happens by mistake is clearly not possible.

dial feet would be the only thing that would prevent this, right? Rest of the movement shouldn't care (since the date is still always on the 'right' side).

Not easy to tell, but THIS (https://urdelar.se/products/dial-omega-seamaster-cosmic-2000-grey-cal-1012?variant=32947275661397) makes it look like the locating pins might be symmetrical? IF THEY ARE, I GUESS I could see it being 'possible' it was done inadvertently (in a "I took it apart like 6 months ago and have been waiting on replacement parts forever, and forgot it was left-crowned" kind of way), perhaps done intentionally by a watchmaker.

IF they aren't symmetrical, it would have to be intentional of course (or at least REALLY dumb) since you'd have to re-do dial feet.

How many dates are there on the date indicator?

Is it an even number?

That is your answer if this is an “accident” or not, regardless of the dial feet…

Oh! Of course! Thank you. I spent the time trying to make sure the date would be the right way around I didn't even think about alignment.

Appreciate you entertaining my curiosity.

Thank you Erich and Archer for your valuable contribution - much appreciated.
That explanation makes a lot of sense. Also, I was thinking the same: if the dial/movement/date setup was accidentally misaligned, the date would almost always appear off-center in the window (since it’s a 31-day date ring), but on mine the date looks perfectly aligned and centered, so it seems unlikely to be a random “mistake” assembly.

Space22 · Jan 29, 2026

You see a few of up-side-down ploprof 600s as well. You are correct, there is a second date wheel available which makes it possible to turn around the movement and the dial in the 600, as well as the 1000, since the dail feet are symmetrical. Archer is right, its can't be done 'on accident', but surely intentional with another date wheel.

Archer · Jan 29, 2026

I've made watches into "destro" models before, and I took this photo to illustrate exactly this point, because a lot of people miss it. This is an IWC with an ETA 2892, and it starts like this:

If you just flip the dial around, you get this:

So you must have a different date indicator in order to get the final result to look like this:
