Up for sale is my Icy Sentinel in 40.5mm case diameter by Northern Star. If you get a chance to talk to the owner, you will find that this watch was a labor of love, as with most microbrands, but also a labor of faith. This is a truly unique and cool design for a watch. The teal and white mother of pearl dial are really a bold statement. The lumen Roman numerals are great and a classy touch. The brushed and polished case is finely made. The lug to lug is compact and very wearable at 44mm. The crown is a twisted design, and screws down with 50 meters of water resistance. The watch is also a slim 10.10 mm tall. The movement is a premium Miyota 905S. The included leather straps are thick and soft, and the included rubber strap. No trades please. I will entertain a best reasonable cash offer. Please check out my other listings. Thank you for reading this. I also did a review of this watch here on Reddit.
