Looking for a omega 1603 module (Frontier 2005A)...

Post31 May 2014, 17:08

Hi there,
Since I stupidly cracked an omega 1603 module after having it successly repaired (GRRRR), I am looking for a new Frontier FR2005a module (omega 1603). If you know other watch models that use this module I am also interested.
Thank you
Chris

Ole Joe has a supply of these and other Frontier modules; I am sure he can help you.

Unfortunately I do not have anymore 2005 modules, only 2006 & 2007.

Thank you Bruce and Joe for your reply.
And i imagine 2006&2007 modules cannot be adapted to fit an Omega constellation 1603 ?

Well, I've never tried implanting either a 2006 or 2007 in an Omega case, but I have implanted them in a couple of Hamilton cases successfully. The 2006 or 2007 ceramic substrates are not interchangeable with the plastic carrier of a 2005 or it would be a slam dunk. Both the 2006 & 2007 contain either a 2005/2015 integrated circuit for the real time portion of the chronograph or alarm modules, so either would look and work exactly the same as the 2005. There's a problem using either a 2006 or 2007 because of the battery clip. The clips for the 2006 & 2007 are different from the 2005 and the clips of the 2006 & 2007 are also different between themselves. It just so happens that the battery clip from a 2006 will fit the 2007. So the bottom line is either, find a 2005 module for a direct replacement (best bet), a 2006 module with battery clip, 2007 module + a 2006 battery clip. I could help you out with either a 2006 or 2007 module but I don't have battery clips for them. Confusing, you bet it is, nothings ever easy when trying to fit a round peg into a square hole.

Hi Ole Joe and thank you for your accurate reply (as usual :)
It seems to quit difficult to use 2006 and 2007 modules as fas as I understand your explainations :)
I bought an Hamilton QED a week ago and it uses nice dot Frontier 2002g. I have not tried yet to see If it fits the omega 1603 plastic carrier but I will :) Unfortunately the 2002g does not have the day of the week function of the 2005a. I saw that some Hamiltons QED (with segments) have the day of the week fonction, would you know the reference of theses modules by chance ?
For my personnal knowledge, which brand and watch modeles use the 2006 and 2007 modules ?

The Frontier 2005, 2006, 2007 all used a "segmented" displays and indicated the "Day Of The Week" as MO, TU, WE, TH, FR, SA, SU. Hamilton used both the 2006, 2007 modules, not sure if they used the 2005, my bet is they did to replace the 2002. The 2002 & 2005 modules were the same size if I remember correctly, so Hamilton wouldn't have had a fit problem if they did upgrade from a 2002 to a 2005. As far as the companies that used Frontier modules, my memory of 40 years ago is a bit vague. Hamilton used the 2006 & 2007, Breitling the 2006, Mercury Time the 2006 and Lanco also used the 2006.

Hi,
I managed to find a Frontier 2005 :) (not an 2005a) in a "sold for parts" watch ! Its works except the first digit :( so the base of this digit seems not connected (else I guess it´s a faulty driver or calculation iC?)
No corrosion on board links...I read in other posts about "dead digit" that it could come from "dry solder joints" between display and board but who knows which connection pad to check for the first left digit base ? I cannot see which circuit board wires go to the driver chip since chips are covered with black resin or silicone...
The one closest to this digit in the uppercut left corner (when facing the display) ?
If someone has a picture of this module without its protection resin, It also would help me :)
Thanks for reading

Hello Chris,

The "display stick" on Frontier modules were mounted using silver bearing epoxy, they were not soldered. If the first digit, that is, viewing the display from left to right is completely out while all others are operational, its most likely the electrical connection from the substrate to the "ball" connection on the display stick, a bad epoxy joint. This would be the "K1" (common cathode) of the first digit. It could also be a broken wire bond from the digit driver to the substrate trace. Don't attempt to get to the digit driver chip which is under the black silicon rubber coating, you will definitely break several wire bonds for sure. Turn the display on in the "set" mode so that the first digit should be indicating a "1" or a letter, S,M,T,W,F and then apply a bit of pressure to the lower left side of the display. Bad epoxy joints will usually show up with pressure applied and go out when released. If this is the case, then all the wire bonds under the black blob are good and the fault is in the joint. The display stick can be "popped" off using the blade of a hobby knife with ease, putting it back on with conductive epoxy or "wire glue" (Google "wire glue" for info) is another story, one which I haven't read yet so to speak. Attached is the Monsanto data sheet showing the layout of connections for the display. I hope this will help you getting the module to work properly.

Joe

Wow, once again, what an answer !! Thanks a lot. I was not planning to remove the black rubber coating, I had guessed it would broke the wires between chips and board ;) i thought the display was soldered but I wondered how they soldered it :) you gave me the answer. :) the diagram you gave and your instructions will be very helpful for a try this week-end, I will keep you informed ;)

It might be worth trying to poke some silver epoxy in under the edge of the display for that K1 connection. If I read it correctly, it's connection 15, which looks to be directly above the digit.
I've used a needle to do this before. Be careful, and make sure you don't short anything else.

Hello,
To end this post "properly", I tried to put a conductive ink drop on the K1 cathode and the corresponding circuit connection but with no result :( after that, I decided to check the connection between the circuit and the display with a 1.5v batterie to see If the defective digit lights up and it does ! So the problem is not a bad connection problem but a chip problem (I would say the power transistor that feed this digit is dead). I should have tested this before :)
Anyway thank you Joe for the mosento display diagram, it helped me ;)
