Help me a pick a high-end "dressy" watch - Lange? VC? Something else?

[Eapfep]

Hi all, I'd love to get some recommendations on a dressy watch between $20K-$30k!

My (small but hopefully diverse) current collection consists of the following:

• Rolex BLNR on Jubilee
• Omega Seamaster 300M White Wave Dial
• Glashutte Original PanomaticLunar Blue Dial

My personal philosophy for the last few years has been to never let my collection outgrow my 3-slot watch roll (+ one on the wrist), so I'm now on the hunt for something truly special to celebrate both becoming a father and getting my MBA next year.

A couple of criteria:

• <$30K USD, I'm selling a watch or two (not listed above in my main collection) to fund this
• Stealthy - so white gold / stainless steel and nothing that is auspicious or draws undue attention
• I think I have my sports watch needs covered, so looking for something that fills a similar role as my GO - dressy but not necessarily a true dress watch
• White / Silver dial so I can have two dark and two light dials in my collection
• Has some visual "interest", I have a history of getting bored of plain white dial dress watches and flipping
• <50mm lug-to-lug

Pieces I've been considering:

• Lange 1815 Up Down in WG
• Lange Saxonia Outsized Date in WG
• Lange Sax-o-Mat 308.025 Platinum
• Vacheron Constantin Historique Triple Calendar in SS
• Vacheron Constantin Traditionelle Small Seconds in WG

But I would love to get this group's very knowledgeable thoughts!
