The Breitling Watch Source Forums

Hello everyone,
I am writing this to ask the question; by using the reference number list here in this forum, are you a little confused?
I, as of today am the proud owner of a Chronomat B01. The reference number on this watch is IB0110. In the list here on this forum the letter (I) is said to not be used and B is.
1 – Case Material
A = steel bezel/case
B = steel bezel/case/gold riders
C = rose gold bezel/steel case
D = yellow gold bezel/steel case
E = titanium bezel/case
F = 18k bezel/titanium case
G = white gold bezel/steel case
H = 18kt rose gold bezel/case
I = not used
J = 18kt white gold bezel/case
K = 18kt yellow gold bezel/case
L = platinum bezel/case
M = blacksteel bezel/case
N = not used
O = not used
P = platinum bezel/steel case
Q = not used
R = red gold bezel/case
S = not used
T = palladium bezel/case
I can't find a watch that is BB0110 but there are a lot with the reference IB0110....... Am I missing something? or am I looking at this all wrong?
Below is a pic of the back of my Chronomat.
Well there is my question can anyone help?
Thanks

The reference system changed for in house pieces.

As Roff said, things have changed a bit since the intro of the inhouse movement.
The Chronomat 44 now has:
- AB0110 - all stainless steel
- IB0110 - steel case and bezel , gold rider tabs, pushers and crown
- CB0110 - steel case, gold bezel, rider tabs, pushers and crown.
