I recently posted some information about Swarovski’s use of Alpha-Numeric numbering (i.e. serial numbers with a combination of letters and digits). So to give a fuller context I’ve attached a number of tables (the information in the first two tables was previously posted as the first table here: https://www.birdforum.net/showpost.php?p=3777457&postcount=7 ).
ORIGINS
Alpha-Numeric numbering was first used on a limited basis in 1985, and in 1991 it was universally adopted (see the first table).
Swarovski had previously used 6 digit numerical numbering (where the first digit identifies the model and the remaining digits provide a sequential number) on it’s two lines with a large number of models - Traditional binoculars (with 7 different model/numbers sequences) and Metric pattern telescopic sights (also with 7 models/sequences).
The main reason for the adoption of Alpha-Numeric numbering was most probably the 1985 introduction of the Imperial line of telescopic sights (i.e those with a 1” diameter body, primarily intended for the North American market). There needed to be a way to readily distinguish by serial number alone, both between the Metric and Imperial lines and between the models in each line (the same type of problem - distinguishing between the various Traditional models by serial number alone - was the impetus for the introduction of 6 digit numbering in the 1950’s - see the table ‘Trad Leatherette Numbering’ in my previous post.
CONSTRUCTION
Alpha-Numeric numbering contains three components (see the first two tables):
- a product line or model identification (the letter);
- a dating component, and;
- a sequential number (5 digits, as of August 1991).
For the user, the big advantage is the ability to readily date a unit - the date is an integral part of the number.
USE
I’ve attached three tables that show the use of A-N numbering:
- for the Early and Transitional periods (1985 to August 1991), then;
- from August 1991 in alphabetic order, and;
- from August 1991 by product lines.
NUMBER BLOCKS
In October 2011 Swarovski modified A-N numbering with the introduction of 10,000 units number sequences i.e. with the 5 digit sequential number component, the first digit now identifies a product type (see the final table in the next post). So instead of a potential 5 digit 100,000 unit count from 00000 to 99999, there is now a 10,000 unit count such as 40000 to 49999. The advantage is that with the increasing number of models, models from different product lines can have the same Alpha prefix but be readily distinguished by the differing number blocks.
I hope this info proves to be of both interest and use to many.
