勞力士,罕有,不銹鋼自動上弦鏈帶腕錶,配中心秒針,“Submariner”,型號5508,約1959年製
Reference 5508 was produced from approximately 1957 to 1961 and was the last Submariner reference to be produced without crown guards with a waterproofness guaranteed to 100 meters. An upgrade from the reference 6536/1, the timepiece featured a small crown and a newly designed bezel with divisions for the first fifteen minutes, larger silver triangle and luminous bubble. The present lot is fitted with an early and very rare service dial with glossy finish with "swiss - T<25".
