Hi guys,

I'm considering buying an Holder Block to keep my bracelets stable while adding/removing screws to size them.
Bergeon is proposing 2 references which have different slot widths:
6744-P, standard one : slots of 2.2, 2.6, 3.0, 3.4, 3.8, 4.0mm
6744-P1, for "thick bracelet" : slots of 3.5, 4.0, 4.5, 5.0, 5.5, 6.0, 6.5, 7.0mm

My oyster bracelet on the SD4k is around 3.5mm
My 1861 speedy is 4mm
My 3861 speedy is 3mm

For which block would you go?
I'm wondering in what cases would you use the >5mm slots. Seems very thick for a bracelet!

Thx
