I can't seem to find the type of watch I'm looking for.

My specs

• as thin and light as possible given the other specs (titanium?)
• some sort of lume
• legible dial, preferably numbers
• saphire glass
• "never need to take off" waterproof, but no diving will be involved

Nice to have features

• comfy strap or the possibility to change it
• offset crown
• silver color case

I don't care about the movement too much, but I don't like the…

Light & thin, but "tough" is there such a watch? Help appreciated.
