Rolex ROLEX SUBMARINER 5513

The Rolex Submariner was introduced in 1953 with the reference 6204 and was the first waterproof diver's watch in history. This model featured a stainless steel strap and a sturdy case that allowed it to be worn down to 100 meters. Its water resistant capability was later increased to 300 meters. Its unidirectional rotating bezel allows divers to track their dive times and decompression stops. Furthermore, the Rolex Submariner's glowing hands and markers make it easy to read even in deep water. The Rolex Submariner 5513 No-Date is also known as the "2 lines dial", as it doesn't have the "Superlative Chronometer Officially Certified" marking. That's why it was considered the most " affordable " 5512 model. It is water resistant up to 200 meters. The first 5513 models are called "meters first", because the water resistance information is first given in meters, then in feet. The Caliber 1530 was used on the first models, and was later replaced by the 1520. The gold markings were only used for the first 4 years, and were then replaced by white markings. A " Tropical Dial " is used on this reference. Another important 5513 model is the "Milsub". This watch was specially designed for the British armed forces and features an encircled " T " below the center of the hands. This model's reference was first a double 5513 / 5517 reference, then only 5517. In the late 1960s, the water resistance indications were reversed to show the measurement in "feet" first.
