original strap seamaster 1958

Hi all just received this omega seamaster
Cal 471
And case is 2802-5 SC
And a serial number showing 1958
I'm intrigued in seeing if I can find an original strap which would have been on this model and A gasket from the back cover
And what you reckon on polishing/ removing scratches from the original crystal for now then maybe later on get a service
I know the hands are bad especially the second hand just gunk stuck to it lol surprisingly it's been running for over 5 hours and Keeping the same time the seller posted it to me, just letting it wind down after being thrown about in transit winding itself up. would like to hear your thoughts and views/ and advice you have Appreciate it thanks

Okay I appreciate that. Yea its quite light scratch in the middle but towards the left side 9 it may be a little deeper? Crack I hoe not hopefully I can polish it out

I've got one that should work and you can have it. Just send me your mailing address: [email protected]
