This is one I built for my wife's birthday and thought I would share the details with you guys. It pushes the limit on the $500 category.
It started out with a Yuki dial and hands
5513 case from Helenaroo
Swiss ETA 2893
Athaya tube and crown
Tudor folded link bracelet
Slightly aged blue insert from the bay
For variety, extra straps including a Hirsch leather double rib, a blue leather NATO, and a blue nylon NATO.
Lastly, custom packaging.
Here's the unboxing..
Outer box
Inner box custom built from a wine crate.
Custom Cigar box presentation/display box
Inside carries all the right pieces
And a few extra shots.
