I don't think this will work without further effort (or at least, I'd
be rather surprised if it did). Perhaps Adam's secring.gpg is
The reason why the locking didn't work is that your watch is formatted
as a VFAT filesystem, as David Champion guessed. GnuPG uses link() as
part of its file locking scheme, and VFAT doesn't support links.
You have a number of options, one is to use --lock-never as David
Champion suggested; you will of course have to take care not to run
two instances of gpg at the same time. The other option is to make
the secret keyring read-only. Read-only files have no need for locks,
and thus are ignored by the locking code. Of course, read-only files
are read-only, so that may not be useful to you if you want to
actually manipulate your keyring on the watch frequently. Or you
could reformat your watch as ext2 or 3 (or really, anything that
supports hard links).
