Bonsoir from Paris,
I'm a little bit confusing about the references used for 6105-811x models (the “Captain Willard” / "Uemura" references). After a lot of readings and catalog comparisons, I found this :
* The reference of the 6105-8110 models is 61MC 022 in the Japan Domestic Market (JDM) catalogs. In 1975, the reference is changed to YAH028.
* In 1972 US catalogs, the reference is 55029 (i.e for 6105-8119 models).
But I saw in different threads another reference : 55025. What is the usage of this one ? An initial one before 55029 for the US market (very difficult to have US market catalogs!).
Merci.

Geday, Those codes from the catalogs are very unhelpful and are specific to wherever the catalog was made. They also changed several times and I don't think anyone has a full list of them. The better way to go is the case reference from the back of the case. Bonsoir from Paris,

That's a relief, because I read the first post with dismay thinking there was a whole system of classification that I'd been totally naive to for years...

The catalog codes irritate me. I get emails all the time saying stuff like "Do you have seals for a SHTRZ7536A?" WTF is that? Always go with the ref off the back.

It just seems like a lot of extra work to even track those down...I don’t even like the SKX and subsequent nomenclature. Why reinvent the wheel? I realize I’m about to ignite a firestorm here, but it’s always seemed to me like, J’s and K’s aside, we should all be able to live with “7S26-00X0”...although I’m sure there’s some utility to the system that I’m just not seeing.

The SKX007 and SKX009 both share the same case and hence are both 7S26-0020, so if you only use that, then you can't distinguish them. You can also have different dial designs which are not different colours, but the same colour (but with different marker designs and hand-sets etc), which will share the same case reference, but will have different model numbers, in order to distinguish them. It's the same in some cases with Kanji day wheels, e.g. with the new SEIKO 5 SPORTS models, they're in the SRPD range for the international models, but in the SBSA range for the JDM versions which have Kanji-English day wheels. |

Point well taken, and of the distinction of different colorways did come to mind. I guess my point is more than I never really objected to the designation of a single movement and case combination by a single model number, without the widespread use of more granular distinctions (for example, a 6139-6002 is a 6139-6002, whether blue or a true Pogue). It makes for a hassle (admittedly a fairly minor one) when looking parts to have two parallel systems of nomenclature. But I totally get why it matters to many people—different aspects of collecting are important to different folks, and I certainly share the desire to know exactly what I have. Maybe this arises mostly from my interest being almost exclusively vintage Seikos, for which we just don’t have some of that detailed information even if we wanted it (like OP). |
