Part of the restoration of the category 1 historic church, the clock face has been restored with white flashed opal glass from France.
Peter Mackenzie said the glass was cut especially for the 100 spaces, each a slightly different shape.
''It was pretty hair-raising. I didn't have a lot of [spare] glass up my sleeve. I had to do the cutting pretty much perfectly with no mistakes to get the job done. So it was a little fraught.''
The clock faces had been ''a bit of a mess'' previously, because of the different types of glass that had been used over the years.
''It looks gorgeous ... It looks absolutely heavenly,'' Mr Mackenzie said.
New dials were also sourced from France, with a fifth one ordered in case a spare was ever needed.
In the next couple of weeks, the clock would be marking the hours once again, after a visit from the clockmaker to reinstall its mechanisms.
