That's a watch you would wear for daily use. Sought after models are watches that have desireable characteristics, such as complications (chronograph, day, date, month, phases of the moon ) etc...The reputation of watch company is also factor.( Patek Philippe, Vacheron Constantin, Audemars Piquet) are famous watch makers whose watch values are a premium. Physical attributes are also a factor, such as gold content, size of case, and whether the case has so called "fancy lugs ". Watch collecting definately has some personal tastes, so if your not too concerned over money, then collect what you like ! From an investment standpoint I would stick to the more mainstream investments such as realstate, gold,
silver, stocks, bonds, etc...
