Quick Answer
Two 38 mm Hamilton field automatics with the same H-10 movement. The Murph is the design piece and costs more; the Khaki Field Automatic is the plainer, cheaper way to the same mechanics. If the Interstellar dial is not the reason you are buying, the Khaki Field Automatic is the better value.
These sit next to each other in Hamilton's own catalogue and are easy to confuse: both are 38 mm steel field watches on the H-10 automatic with an 80-hour reserve. The separation is design and price, not specification.

Selection Time Verdict
Choose the Hamilton Khaki Field Murph 38mm
Choose the Murph 38 if the dial is what you want — cathedral hands, beige lume, no date, and the Interstellar connection. It is the more distinctive object and the one people recognise.
Read the full reviewChoose the Hamilton Khaki Field Automatic 38mm
Choose the Khaki Field Automatic 38 if you want the same movement and the same case size without paying for the film association, or if you prefer a date window and a more conventional field dial.
Read the full reviewMechanically there is very little to separate them: the same H-10 calibre, the same 80-hour reserve, the same Nivachron hairspring and the same 38 mm case class. The Murph asks a premium for a specific dial design and a story, and whether that is worth it is a question about you rather than about the watches. What tips the practical argument is the strap and the date: the Murph is leather-only and dateless by design, while the Khaki Field Automatic offers a more everyday configuration. Buy the Murph because you want the Murph. If you are comparing spec sheets to find value, you have already answered the question.

Frequently Asked Questions
Do the Murph and the Khaki Field Automatic use the same movement?
Both use Hamilton's H-10 automatic with an 80-hour power reserve. The Murph 38 specifies a Nivachron balance spring on its product page.
Is the Murph worth the extra money over the Khaki Field Automatic?
Only for the design. The mechanics are the same class. If the dial and the Interstellar association do not matter to you, the extra spend buys nothing measurable.
