PRX Powermatic 80
or Khaki Field Murph 38?

The quick answer.

Choose the PRX for its angular steel case and integrated bracelet. Choose the Murph for a compact field-watch design and a conventional leather strap. Official US prices are $850 for the T137.407.11.041.00 and $995 for the H70405730.

The proportions.

The T137.407.11.041.00 has a 40 mm case, while the H70405730 measures 38 mm. Compare thickness and bracelet construction as well as diameter. Our fit tool uses verified lug-to-lug measurements where the manufacturer publishes them.

Make the choice around your routine.

A buyer drawn to a clean steel sports watch with a distinctive bracelet. The PRX Powermatic 80 is the one we would explore first for that use. Someone who prefers readable numerals, leather straps, and a quieter dial. The Khaki Field Murph 38 takes the other direction.

Before you order.

The integrated bracelet shapes the fit. Tissot publishes case length, which is not a verified effective lug-to-lug measurement. There is no date display. The official page does not provide lug-to-lug, so check the watch on your wrist before deciding on fit.
