The Seamaster series features three more interesting models: the Bullhead, the Railmaster, and the Aqua Terra 150. The
Bullhead is of particular interest, as its shape resembles that of a bull's head and it is popular among both collectors and fans of unusual timepieces.

The most recent models can withstand up to 15,000 Gauss and sell for around 4,000 USD. Prices for models from the 50s are 60s can quickly rise to about 15,700 USD.
In the Aqua Terra line, Omega combines the straightforwardness of a tool watch with the elegance of a dress watch. The various models are available with gold and diamonds as well as mother-of-pearl dials and crocodile leather straps. You can get a simple model in stainless steel for as little as 4,000 USD. Those with a GMT or chronograph function require an investment of around 5,800 USD. When gold and diamonds are added to the mix, prices can range anywhere from 13,200 to 40,800 USD.
