The smaller 38 mm San Martin is made of solid stainless steel with screw-down signed crown and screwback (water resistant 100 M). AR coated sapphire crystal; luminous hands, numbers, and marks; 24 jewel Seiko NH35 automatic movement; and 19 mm aviator style leather band with signed stainless steel buckle. The larger 44 mm Rugged Maine. Watch is made of solid brass with screw-down crown and stainless steel screwback (water resistant 50 M); mineral glass crystal.
Luminous hands, numbers, and marks; 25 jewel "open heart" Sea Gull ST2501 automatic movement; and 22 mm leather band with large stainless steel buckle. These are very nice examples for any collector of aviator watches.
I have a large collection of them and decided to let these two go. Good luck and thanks for looking.
