Hamilton Railroad Lady Quartz Steel H40311191

The case is 8.9 mm thick and water resistant to 5 bar (50 m), with a sapphire crystal over the dial. The lugs are 14 mm apart, and the steel bracelet closes with a folding clasp and uses Hamilton's Easy Click quick-change system.

The H40311691 is the same watch on a NATO strap instead of the bracelet. The H40311121 swaps the mother-of-pearl for a champagne dial, and the H40391191 keeps this dial and bracelet and adds a diamond-set bezel. The Railroad Lady Automatic H40405191 pairs the same mother-of-pearl dial and bracelet with a larger 32 mm case, the ETA 2681 and a date.
