Sun Company Slip-On Wrist Compass - Easy-to-Read Compass for Watch Band

Nice purchase, woth buying.

I'd just received this slip on compass, so can't properly report on any long term durability or reliability. What I can share is that, out of the box, the compass is functional and relatively accurate. Currently clear with no bubbles. It will slip on easily and perfectly onto a majority of 22mm NATO/G10 styled straps. Any smaller and there may be a bit of play. With a bit of effort, I can squeeze this compass onto a couple of my 24mm Zulu styled straps as well. It is a closed system, so slip on versus clip on to straps. Lume is okay. Hope this info helps.

It’s fairly accurate it’s off by a couple of degrees but at it’s size and price it’s pretty good slightly too big for my watch but all in all I’d recommend this compass if your looking for something small and easy to read if you need something to be precise I’d recommend a bigger and more expensive compass,

まだ一度しか使っていないので耐久性等は分からないが、腕時計のベルトに付けていると、方位の確認が実に楽、そのため頻繁に確認できる。防水も良。磁針のブレも少ない。これだと旅先の街中で付け方位を確認してもおかしくない。アイデアよく、優れものである。

Great until it isn’t. Does not like the cold. Lasted one season. Bubble formed at -20C and just got bigger when it warmed up. Never cleared.

到着翌日には装着して使用しました 大きさも丁度良いと思いますし、バンド装着の方位磁石として優秀だと思います。（低山ですが！） 特に泡もなし！ 満足です
