Sinn 1736 Classic is a good one alongside the other suggestions.

There ate also 10k cars and 3mil cars. For me 5-20k is reasonable for a luxury watch. Obviously this is only for enthusiasts.

If it´s expensive, mechanical. Shame to waste precious metal and gems on a quartz. If your budget is over €500 I´d go for a mechanical watch. If under, quartz if she will wear it on occasion only.

Yea, it´s just for an idea of what looks good with gold.

Gold case + dark blue dial + leather strap. My favorite is blancpain villeret quantième complet

No, I´m new to them/wouldn´t recognize the type if I saw one. Why are people rude about this? I couldn´t find the model, so I asked here.
