Shops In Denver

Are They Any You Recommend, If You Are In The Denver/Aurora Area? I'm Into Antique Things Like Those Mentioned In The Title, And I Want To Buy Myself A Pocket Watch For My Birthday, I Love Them. Antique Hunting Sounds Fun. So, Are There Any Shops You'd Recommend?
Also, The Type Of Pocket Watches I'm Specifically Looking For Are Skeleton Pocket Watches, The Ones That Let You See The Gears Inside.
