Not sure what you are asking here. Are you asking does it have the 1120 vs the 1109 earlier version of the 2892 or are you asking vs the quartz 1538? The 1109 was used for roughly a year from 1994-95. You can’t identify it externally vs the 1120 but it is only seen in the very first tritium lume watches. The quartz 1538 can be easily spotted from the date window spacing and dial text, though some early auto watches also lack the Chronometer statement too so be careful if just going on the text.
If a 2531 ie a Bond Auto has SL lume, it has a 1120. If it has fried egg tritium lume it could have either. There actually isn’t all that much difference in the auto movements, both are 2892 derivatives. There may be a way to tell if a given watch has the 1109 from the serial. Very early auto Bonds were in the 49m or 54-55m range (serials jump about in this period). In my experience your watch has a 60m serial or higher it will have the 1120, regardless of dial lume. Confusingly the quartz serials follow a different pattern so don't assume an auto and quartz with similar serials were made at a similar time. There were several ETA 2892 versions in use by Omega in the 80s and 90s, the 1108,1109, 1111 and 1120. Indeed the later 2500 was based on the 2892, though Al will slap my wrist if I suggest they are too similar since many (the majority?) of parts have been redesigned.
