Is there a difference between the crown stem length of Sub versus SD?

[subgmt]

Hi sorry that if this was asked before,

I was comparing the Sub versus the SD 4000. After unwinding each crown on both SD4000 and the Sub 16610. I feel that the Sub has a longer crown stem length when you pull out the crown and the SD seems shorter....

Is it true or there is something wrong with the SD4000 i was handling?

Comparing the Sub to the Daytona,I was handling the Daytona at the AD, it has the shorter stem length when you pull out the crown, is it due to non-date calibre?

Hope some tech expert could advice. Is this due to the water resistance ratings or just the unique design of each piece. thanks.

When you replace a stem it comes in at a standard length which has to be trimmed for each job and they all vary. there is no set length for any particular case configuration,variables such as depth of the threads in the crown itself will vary from crown to crown so just changing a crown onto an existing stem doesn't mean that you don't have to adjust the stem by shortening it. Sometimes they have to be replaced because the crown screws on too deep on the stem to function properly. Hope I didn't get to convoluted Rik
