very nice.
The American Standard Watch Case Co was founded in 1920 and We think the Bulova W. Co hallmark on the movement pre Dates 1923.
1920 - 1923 with 1921 being a very good production Date estimate.
6PPI is the Movement model.
ad Dated Dec 1922 http://www.mybulova.com/sites/default/files/vintage_ads/1922-Bulova-Dec…

The semi-circular bits at either end of the Case being part of the strap.
6716-S, 1922 if We follow the ad.
is anyone else jealous?
