Get higher on the AD list?

[Wilmslow]

I have a Rolex purchase history with my AD (3 sports watches and a date just 41mm) in the past 2 years, however, I am awaiting a call for a new Ceramic GMT Pepsi and/or a new GMT "Batgirl". Thing is this - I also need to buy my girlfriend an eternity ring later this year (am thinking of paying circa £3k). Is it worth "hinting" I am more likely to buy the eternity ring with my AD, if I get an early call from them for my requested watch? Thoughts appreciated.
