Hamilton is introducing a 38mm size along with a range of new colourways to its Field Titanium Automatic collection.
The family of field watches was previously available in 42mm versions.
That size will continue to be available, and there are new models in 42mm, one with a blue dial, the other in khaki.
Both sizes use the H-10 automatic movement with 80 hours power reserve and Nivachron balance spring.
38mm Hamilton Field Titanium Automatic watches are priced at $895 to $945.
The 42mm version costs $945.
