SKX013 Brushed Black Chapter Ring - White Markers [ULTRA THIN EDITION]

Thinner than before. OEM was at 2mm width. We shaved it down to 1mm width for all our SKX013 chapter ring. Now with the Ultra Thin Edition, we further shave it down to 0.75mm width. A huge 62.5% reduction in width.

This helps to have a sightly more discreet chapter ring or to accommodate dials with indices that sits at 27mm and less.

A brushed black with white markers chapter ring designed specifically for the replacement of SEIKO SKX013 original plastic chapter ring. An excellent cosmetic enhancement to create a lush and clean visual.

**Note: Due to the thinnest, white markers are very tiny it may not be visible for some individuals.

Dimension of this chapter ring has been customised for greater clearance, perfect fitting and pairing of our dials onto SKX013.

Made exclusively for us with quality assurance by ISO 9001 Certified manufacturers.

SeikonL SKX013 chapter ring

I ordered only a very small part. Adriel was very kind and professional, I got continous info about the status if the delivery.
The handwritten note came with the item was very kind an personal.

Exactly What I Needed

This is a perfect fit if you need a chapter ring with a larger inner diameter than the original skx013 chapter ring.

Perfect fit

I like some others who reviewed this item, hastily bought the incorrect chapter ring for an SKX013 build that did not fit the dial I wanted to use. This chapter ring fits perfectly now!

This chapter ring is a perfect fit.

It has high dimensional accuracy and fits perfectly on the SEIKO Mini Turtle dial.

SKX013 Thin Chapter Ring

I was pretty hasty when planning my 013 build and was not aware that standard chapter rings may not fit all dials in this sized case. Luckily Lucius Atelier had a thin chapter ring that fit perfectly. I paid a little extra for expedited shipping and it was well worth it. Great fit and finish and shipping was timely. The hand written note from Adriel was icing on the cake - little things like that show that owners are truly engaged in their business and care about customer satisfaction. Would definitely order from here again.

Not thin enough

Even though this is advertised as allowing more clearance for a variety of dials, it doesn’t have enough clearance for my seiko Mohawk. Great quality and I’ll buy from Adriel again but can only give 3 stars this time.
