I recently found sources of inexpensive sapphire crystals and watchmakers would can replace them.
This got me thinking - I can get watches with good looks & movement, replace with sapphire, and voila, I get myself a keeper.
In talking to a guy about replacing a 40mm crystal, he chuckled and said - don't blame me if it breaks.
I asked another guy, and he also tried to talk me out of it.
Does anyone have any insight on this ? Is 40mm too big for sapphire due to its brittleness ?
The standard size only goes up to 40mm, thickness comes in 1mm or 1.2mm. Is 1.2 thick enough for 40mm ?
maybe I should opt for the dome crystals (1.3mm thick, I am told). Are dome crystals inherently less likely to break - is that why most big face watches have dome crystals ?
The Bell&Ross is gotta be at least 40mm across too, no ?
