Hi guys,

This is my first post although I have been soaking up tons of knowledge from the kind members here. Feel grateful to have learnt so much in such little time and super impressed with everyones generosity when it comes to knowledge sharing.

So i recently came upon my grandfathers watch that he bought from the USA in 1957-1958. Although my granddad passed away almost 2 decades ago, dad had always mentioned this watch and it miraculously turned up a month or so ago at a couins place in a box. He was moving house and he sent dad a box with some of grandpa's old stuff and this watch was in it!!! A pleasant surprise. The watch is in Melbourne, Australia by the way. I am going to try and have the watch restored to as near as possible to the way it would have been when grandpa bought it.

I restore old Honda speedometers so I had some sharp fine tools and the case back came apart easily. Pictures attached.



After scouring online for information I was looking for some answers, if anyone can be so kind as to point me in the right direction:

1. The hands do not seem original. Dad recalls the watch was sent to Omega for a service in the late 80's or early 90's overseas perhaps in the UAE region. I believe the hands should be the dauphine non lumed hands as I cannot see any lume remnants in the chevrons? Was there a non lume chevron hour markers?

2. Can anyone tell me the length of the minute, hour and sweep hands? I will begin my search for them.

2. The crown is missing but I have been able to source a NOS chevron crown, signed, albeit its not the one with the flat feet so I am assuming it would be from a later omega? Does anyone know the transistion year(s) from when Omega moved from the flat feet omega symbol to the current day one on the clover crowns?

3. The bezel is missing. I plan on getting it restored and serviced and Ill wear it without the bezel till I can source one. All my research has shown these bezels are made out of unobtanium and are as rare as hens teeth to find. I understand my best bet would be to get a cheap 2846 series case and salvage it from there?

3. Finally, would one be able to put a year for this watch? The movement is a cal.500 with serial 145xxxx and case is a 2846-1SC.

I am pretty excited about this watch and the journey of learning it has taken me on and grateful for everyones help and guidance in advance!!

Also I handed the watch over for the service to J. O'Donnell in Melbourne. They are a 100+ year old business and came highly recommended from a few local watch collectors who I happen to know.

Welcome to the forum and best of luck with the restoration. Delivered circa 1955. I agree that the dial markers most likely had lume dots at the outer end originally. You might see some remains under UV light, but maybe not.

And dauphine hands would make sense. On a dial like yours, the sweep and minute hand would typically extend to the minute track, fully overlapping the small printed markers. But you know, sometimes Omega made some odd combinations. So just to be safe, before starting to replace things, I'd do a google images search and collect a bunch of photos of similar examples.

Thank you Dan.

In regards to the lume dots; was there a variant with these markers that were without lume? If not then they probably did have them at some point...

Cheers
