Info required ref mid 1920s Omega Tank 43mm

Photos show my mid 1920s 18carat gold Omega Tank ... fairly large tank model ie lug tip to lug tip 43mm; 25mm wide ... 27.5mm with crown; between lugs 22.5mm. Movement SN 6516255 ... case No. 6527395. Extensive service dates/marks on case back interior.

Can members please advise:
1) Would this watch have had an Omega model reference ... and if so which?
2) Should the movement number and case number be the same ... I'm wondering if the movement may have been 'swapped' at some time? Or is it usual for the two numbers to differ?
3) There is a circular surface hairline on the dial from 10 to 2 ... indicative of the minute hand touching the dial ... e.g. if pulled crown was turned when movement was out of the case. Hairline visible when viewed at an angle ... please compare last two photos. What might opinions be regarding a possible 'redial' ... or would it be better to leave the dial as is, i.e., original?

Watch is running but a little erratic ... hopefully a service will improve its timekeeping.

Custom Condor croc. strap was fitted a few years ago ... but I've seldom worn the watch.

Thanks for reading ... this is my sole prewar Omega

Hi @dunk_S and welcome to this forum.

I cannot answer your questions specifically, but somebody must break it down to you: the dial of your watch has been very poorly repainted.

6516255 is also the serial number, not the movement.

Thank you ... I have seen worse vintage Omega dials ... So... maybe no harm in seeking a quote for a better quality redial? The Omega logo has been queried for being 'too wide' by TZ UK members (where I'm a regular member) ... but at the time I discovered similar 'wide' logos in Omega books.

I too have seen worse redials. This one is fine enough. Obviously affects collectability but not wearability per se. Looks good for an oldie!

most objections have been raised. Something else and easy to do: if you have it serviced, ask your watchmaker to take the glass out and clean out the very poorly applied, and smeared all over, crystal glue. glue it in clean again and it will make a big difference. enjoy ! kind regards. Achim

Thank you Achim ... Crystal cement smears noted

Received a dial refurbishemnet quote ... £165 plus insured shipping ... so when funds permit I may send dial for restoration. And the glass removal / clean-up / re-cement s/b within my capabilities (using acetone). I checked the dial restorer's 'completed' photos and they look fine ... If completed to the same standard the restored Omega tank dial should be a great improvement.
