Question on Rolex clasp codes

[easy_beaching]

So I came across this 93153 and I noticed the clasp code was only listed as "H" putting it's creation in the year 1983. However, I thought all clasp codes had a letter and a number denoting the month it was created. Is this likely a replica or is this something that occurred with genuine Rolex bracelets?

Bump, really curious if anyone has some insight on this one.

You can find other gens without the date number on the clasp online. Rolex has never obsessed about these things like consumers do.

I figured as much. This is the first I've come across and was genuinely curious. The price is also attractive compared to others so it had me questioning it.
