Serial Number 1836108 was reported as inaccurate.

Note: Run quantity is wrong. Bunn Special marked
“Extra”, 8th damaskeen pattern is very limited
production - somewhere around 500 total if memory
serves. I can look it up if you’d like.

Total production you show would be for the grade;
i.e. all model 6, 21j 18s Bunn Special variants.

It would be very helpful if the individual
variants were described separately with total
production for that variant listed along with the
total production for the grade
Curator Response: Thanks for the report. Correct, the production total is for all 18s Model 6 Bunn Specials to be consistent with metrics across other grades. Applying different accounting for certain grades would be not properly represent some variants. You are viewing it from just this particular watch, but the entire database must be considered when making decisions on how to display production totals in a consistent manner.
