EMPTY WATCH - Designer Wristwatch - any 20mm strap

Hi guys!
It's my designer watch project! EMPTY WATCH - everyone who will notice it will be in a shock!

You DON'T need spring bars to attach strap! You just need to cut 25mm of filament! 20mm strap fits into my design :)

Please, give me your feedback!

PS: I used some top layer pattern on my print, it doesn't looks good, but my print profile is using normal one!
