My dad is retiring in a few weeks and his company is giving him a Rolex to commemorate the occasion. He told me that the Seiko I gave him as a gift years ago suits him just fine, and he knows I have an interest in watches, so he's generously decided to give the Rolex to me, and he wants me to pick one out.
The default model they offer is a Datejust 36 (steel/yellow gold, fluted bezel, jubilee bracelet, white Roman dial), which is listed at $11,200, but I can choose any Datejust (36 or 41), Oyster Perpetual, or Cellini around the same price. If my choice is more expensive, I can pay the difference at a 20% discount; with this in mind $15k is probably my upper limit.
I'm a man in my early 30s and I work in SF bay area tech; most days I wear a button-down shirt and jeans. I'd ideally like a watch that fits this general formality level, but can be dressed down to a T-shirt and up to a suit if possible. I also own a Nomos Tangente (formal-ish IMO) and a Junghans Max Bill that I keep casual on a NATO strap. I'd been thinking of rounding out my collection with an Omega Speedmaster Pro before my dad offered, but this Rolex will probably be my last timepiece acquisition, and hopefully my everyday wear.
The Cellini models are beautiful but they're fairly formal and start at $15,200; the Oyster Perpetual models are all under $6k. That leaves Datejust, and I'm thinking 36mm instead of 41 for a 6.5" wrist. My generation seems to consider visible (i.e. yellow/rose) gold ostentatious, so steel/white gold might be best. I like the fluted bezel/jubilee bracelet combo as it seems easier to dress up than the sportier domed/oyster pairing. (Correct me if I'm wrong on any of these assumptions.)
I originally settled on the Datejust 36 M126234-0017 (steel/white gold, fluted bezel, jubilee bracelet, blue sticks dial) which goes for $8,200, but my dad is hesitant to leave $3k on the table. He's suggested various models over $10k with the following color codes: [0027 (black), 0037 (blue), 0019 (mother of pearl), 0029 (silver), 0021 (aubergine)], but they all have diamonds, and I'm worried they might be too flashy or feminine. He's been insistent about the $10k minimum, and I want to respect his wishes since he's giving me the watch after all. What would you choose?
TL;DR: Recommend a versatile Rolex Datejust between $10k-$15k (USD) for a ~30yo male tech worker?
P.S. Sorry, I tried to include links to the models but my post count isn't high enough yet!
