Identity crisis; even on official papers! 1550 or 15505?

[CLH15]

Hi, i just bought this watch from an ebayer with a good reputation etc and the watch comes with all box and papers.

However i am utterly confused!

The model number on the lugs says its a 1550, the official certificate says its a 1550 but the watch was serviced in 2011 and the service card says its a 15505?

A few things to note is that during the last service, the watch had a replacement dial, replacement oscillating weight and a new bracelet - all done by rolex!

I hope someone could confirm what the watch is by pointing me in the right decision.

Thanks in advance.

It's a 1550. RSC always do this, eg. 1675/0, which means the service covers both models.

Oh i see,

how come there are some bracelets i see with gold plating all-round and this seems to be on the top only?
