15202 ST vs 15400 OR

[tng11]

Long time lurker, first time poster.

I am stuck in a enviable dilemma - I was offered the opportunity to buy a 15202 ST brand new from an AD, which I have been eyeing for years. However, I recently tried on a black dialed 15400OR on strap and also fell in love with it (a 99% second hand one). The 15400OR is a bit cheaper than the 15202 as well given that it's 2nd hand vs. brand new.

My collection consists of a Jarno Trulli ROO, a 26320ST and a Rolex Sub. The JT and Sub are my daily wearers (I alternate days with both), whereas I rarely wear the 26320 as I find it a bit heavy and cumbersome for my 6.75" wrist. The 26320ST will be sold off once I pick either of these two.

I really want to add a PM watch to my collection - but I feel that the 15400OR could be a bit too flashy for my lifestyle. On the other hand, while I like the bracelet of the 15202 very much, it is perhaps a bit too delicate for my lifestyle - and also partially killed my enjoyment of the 26320ST.

Any help would be appreciated!
