Advice on omega seamaster 30 cal 286

Good Evening.
I’m new to the forum and would thoroughly appreciate some advice on a seamaster 30 cal. 286 I’m considering purchasing. I have read a few articles and researched the subject of vintage omegas and found myself on this forum where there seems to be a wealth of knowledge. I was hoping to get some feed back on the attached images. I’m certainly no expert but I have my reservations around the sweeping second hand being original. That said I’m unsure if there were different runs or variations of this model which had the hands shown on this watch. Any other pointers would also be appreciated. Thanks in advance.

Hi,

and welcome to OM.

Second hand is not original - dial might be legit but we would need better pics to give you more information on the originality of the watch.

Hi.
Thanks for the responses. I can try and obtain the numbers. Which other pictures particularly would be most helpful??

thanks again.
