Best Clock?

The clock in my Baron yoke is old, scratched, and otherwise doesn't match
the new interior. The only one available that might fit is a Davtron, which
is not approved by STC.

Therefore, it sounds like I need a 337 and a field approval to install this
clock. Has anyone had a similar experience? It seems like a lot of hassle
for just a clock, although it is a permanent installation, etc.

I bought my aircraft without a clock and wound up installing one that was not
listed on the OEL. Since it ties into the aircraft power system, the local FSDO
wanted a statement of the voltage required and proof that it was manufactured
for use in an aircraft. I had to call the manufacturer to get the voltage and
write up a statement myself describing the conversation. The box in which the
clock came, the receipt, and a page from the Chief Aircraft catalog was accepted
as proof that it was, in fact, aviation equipment. I installed the clock under
supervision and my IA took care of the 337 and arranged for a field inspection
to be performed. The installation, paperwork, and inspection was all done at
annual inspection time.
