1989 DateJust blue diamond dial - verification?

[brodes]

Hi there,

New here, looking for a two-tone datejust with blue dial (diamond markers preferred) as a gift. 1989 is birthyear for the recipient, so I've been looking for L serials.

Found two on ebay and would love some help with any red flags. Thank you for any help.
