As mentionned before, the case offers a 150 meters waterproofness. Same goes for the crystal, hands and tropic strap found on every 62MAS (cf Anthony Kable’s article on the tropic strap in the sources).Ībout the hands, it’s interesting to note that they are not specific to the 62MAS but can be found on several Seiko references like the famous 6105 but also the 7005-8052 «Poor man’s 62MAS» or the 6601-8830 Seahorse (among others).Įvery variation of the 62MAS had bi-rotating clickless bezel and non-screw down crowns, which explains why patina and oxydation are very common on these models.Īnd finally, every 62MAS has a 37,5mm «Skin Diver» type case, with drilled lugs, circular graining on the top and the rest of the case polished. Please give a closer look to the indexes as they are not rectangular but trapezoids ! On the dial side, we can say that every 62MAS has the same dial, minus a few minor details we will adress later. It’s an automatic movement beating at 18000bph, with the quickset date but without manual winding and hacking. We will come back to the specificities of each references later but first let’s focus on their common points.įirst, we quickly talked about it but all the 62MAS use the same 6217A movement. Being a professionnal watch, the functionality of the watch is what prevails here ! So we said that the smaller crown was the reason why the 6217-8000 was quickly replaced by the 6217-8001 «Big Crown», made to be easier to handle with gloves. SCWF member RossR made a lot of research, referencing 300+ 62MAS found online (cf sources for his very interesting article) and estimated, based on the cases’ serial numbers, that about 12,300 Small Crowns were made out of a total of 84,400 62MAS.īut as Gerald Donovan pointed out, it doesn’t seem like Seiko used specific serial numbers for each references they made and we can find other non-62MAS Suwa-made watches with serial numbers intertwined between 62MAS serial numbers, which shows the cases’ serial numbers can’t be used to make an estimation of how many 62MAS were made. This is an important point that explains why this watch was only produced for two months, April and May 1965, thus explaining its rarity today. This reference 8000 is also called «Small Crown» because of…well you guess it, the size of its crown. It was originally made by Suwa but we will come back later on this point. Credit: Anthony Kable As we already said, the 62MAS was released in 1965 under the commercial reference 62MAS-010, but it’s better known under the classical Seiko reference 6217-8000 (the first 4 digits for the movement, the 4 others for the case number).
