Very Rare... It is not always immediately obvious why mechanical wristwatches that could be considered indispensable have complications, but for air passengers, international company executives, news, finance or communications personnel in the 1960s, a watch with a 24-hour display was a necessity. . the function must have a certain useful appeal. Today, even in the age of the smartphone, there is a certain charisma to the GMT watch that appeals to vintage watch enthusiasts, such as the fully serviced and extremely rare 1972 Seiko 5619-7019 GMT automatic. 5619 was produced briefly by Seiko from 1972 to early 1974. Seiko built the 5619 on the same 56 caliber automatic movement as the King Seiko and Grand Seiko references of the period. However, unlike other Seiko GMT models of the time, the 5619 is unique in that its 24-hour GMT hand is not operated by enslaving the 24-hour hand to the existing 12-hour hand, but rather determines the local or GMT time by setting a 12-hour hand. internal clock hand. 24 hour frame. Instead, the 5619 design allowed the 24 GMT hour hand to be quickly adjusted independently; Therefore, there was no need for a rotating frame. The 5619's independent orange GMT time zone hand (see images) is set to the user's preferred time zone via the first crown adjustment (for the GMT hand in one direction, for the date in the other direction). After this adjustment, the orange hand moves with the normal hour/minute hands. This Seiko 5619 GMT has its original stainless steel bracelet, has a very rare black inner bezel and white dial, namely the Panda Dial, and is original. The dial has scratches and debris due to age and wear.
