1984 Seiko Field MasterSeiko ContraSAZ018
" In 1984, Seiko started their FieldMaster series by using their already proven H558 movement and redesigning the watch around the movement. The Japanese are well known for their extreme adventures around the world and they needed a watch they could rely with their lives. This watch was taken on numerous adventures to the North and South poles, Mt. Everest and other peaks of the world.

Because this watch met just about all their needs in a time piece, it acquired the title " King of the Land " For this watch to have received such a title, it had to cover about 20 characteristics, many life saving. Here are some.

1. Water resistance it was capable of a 10 atmospheric-pressure depth.

2. Shock resistance from a height of 3ft. either by dropping a rock from that height onto it or by dropping the watch from that height.

3. Magnetic resistance it could handle 16,000A/m when specs only called for 4,800Am

4. Abrasion resistant crystal Hardlex was used. Sapphire probably would have been better but, wouldnt have stood up to decompression

5. Heat resistance +60 degrees C which is higher than the worlds maximum temperature

6. Cold resistance 2mm thick crystal with AR coating to prevent fogging and glare. It was tested to -40 degrees C without a problem

7. Corrosion resistance it's made of Titanium and will resist corrosion if left in salt water for more than 24 hours.

8. Chemical resistance it can't deteriorate from alcohols, cosmetic oils,

9. Dust resistant sealed against natural environment penetration ( dirt, dust .etc)

10. Gas resistant ammonia gas, carbon monoxide..etc.

11. Luminescence it's able to be read from distance of 25cm in complete darkness

12. Weight made from titanium it only had a total weight of 56grams

13. The case was to have characteristics built in for safety and reliability rounded edges, emergency signal code, compass, shroud for protection "

工具感十足。不过，指南针的磁性和表不会相互影响吗？
