At OMEGA we use a unique number to identify each watch, called a Long Product Identification Code, or PIC, which consists of fourteen numbers.
For example, the De Ville Ladymatic OMEGA CO-AXIAL 34 MM has the following PIC or Long Product Identification code: 425(A).65(B).34(C).20(D).63(E).001(F).
Each of these numbered codes is divided into six lettered groups, A through to F, which refer to the specific details of the timepiece.
For instance, the fourteen numbers of the watch we've just mentioned breaks down as follows.
The first three numbers of the code (Group A) refer to the OMEGA line or family of watches. (425= De Ville Ladymatic)
The next two numbers of the code (Group B) refer to the material of the watch head and bracelet or strap. (65 = gold + other material paved for the watch head and assorted metal for the bracelet)
The following two numbers (Group C) reference the diameter and size of the watch. (34 = 34mm)
The eighth and ninth number of the code (Group D) reference the movement and complication, or the calibre that powers the watch. (20 = Mechanical with Co-Axial)
The following two numbers (Group E) reference the color and the material of the dial. (63 = brown + precious stones)
The final three numbers of the fourteen-number code (Group F) refer to the specific sequence number of the watch. (001= first in the sequence).
AAA.BB.CC.DD.EE.FFFThe first group of digits AAA stands for 130=Constellation Globemaster; 212=Seamaster Diver 300M; 215= Seamaster Planet Ocean 600M; 220=Seamaster Aqua Terra; 233= Seamaster 300; 304=Speedmaster Moonwatch Moonphase; 311= Speedmaster Moonwatch Co-Axial; 329=Speedmaster Racing; 424=De Ville Prestige; 425=De Ville Ladymatic; 428=De Ville Trésor Quartz; 522=Olympic Games Collection; etc. +22
AAA.BB.CC.DD.EE.FFF (Watch/Bracelet)The second group of digits BB stands for 10= stainless steel/assorted metal; 11=stainless steel/other metal; 12=stainless steel/non metal; 25=stainless steel+gold paved/assorted metal; 35=stainless steel+other material paved/assorted metal; 51=gold/other metal;62=gold+other material/non metal; 98=other material paved/non metal; etc. +40
AAA.BB.CC.DD.EE.FFFThe third group of digits CC stands for Size of watch-head, rounded to 2 digits per rules of mathematics.
AAA.BB.CC.DD.EE.FFFThe fourth group of digits DD stands for 1st “D”=Type of movement: 0=Mechanical; 1=Mec. Chronometer; 2=Mec. with Co-Axial; 3=Mec. Chronograph; 4=Mec. Chrono Chronometer; 5=Mec. Chrono with Co-Axial; 6=Quartz; 7=Quartz Chronograph 2nd “D”=Number of complications*: 0=0 complication; 1=1 complication; until 9 *=Considered as a complication if the watch provides more analog indications than jus hour, minute, second and date in one disc. Since the chronograph function is already described in the first digit, it is not considered a complication here. Tourbillon and time-zone are considered as complications.
AAA.BB.CC.DD.EE.FFFThe fifth group of digits EE stands for 01=black; 02=silver; 03=blue;04=white; 05=white MOP; etc. +22
AAA.BB.CC.DD.EE.FFFThe last group of digits FFF stands for Sequence number of the model
