Yea shape similar to the three 158's we have in watch database and various 158 ads. All of those three watches are American Standard cases. Fifth's example has same bezel engraving as subject watch.
Could be a 157 (I know- I'm guessing based on odd/even number patterns for other similar model numbering for fill vs solid gold in this time period, but it's a good guess. A confirming ad would make it a better guess).
