Sorry, but it's a redial.
The script is erratic, and does not match any known 2652.
I own a 2652 with a dome dial and crosshairs, so these do exist. However, mine has the Swiss made signing, which should be on all Constellations from this period.
The crown has been heavily worn, so you'll find it a challenge to see whether this has been replaced or not, but modern replacements for this model are still available.
