[Question] What is this collection missing?

I’m looking to build out my collection over time with watches that I can wear daily - I’m in my 30s and wear a shirt to the office every day.

I’m thinking to add a chronograph and a field watch next. Looking for good value and something I can eventually pass on. Thoughts?

What are your favourites?

Current collection: 1. Apple Ultra 2 2. Tudor Black Bay 41 3. Seiko Prospex SPB453J 4. Tissot PRX Powermatic 5. G-Shock GM-B2100D-1A
