Reply With QuoteDon't know about these but thought compass degrees were always clockwise.
I have 2 Protreks one has the compass degrees clockwise and the other has them anticlockwise, can anybody shed any light on why the difference.
The one with clockwise is a digital if that makes any difference.

Indeed. It's one of those things that sometimes their being the other way around would cause chaos, I'd have thought!Originally Posted by Kingstepper
Edit: Geological compasses look to use the anticlockwise format https://en.m.wikipedia.org/wiki/Geol...ogue_compasses

anymore info anyone, for why it would be on a watch
On the reversed compass, the N marker isn't a N marker in the normal way (although it points N! :D
) it points to the bearing on the reversed scale that the 00 marker is aiming at.
So point 00 at the thing whose bearing you want to know.. the needle is now pointing at the appropriate number on the scale, so you can just read it like a gauge.
Bloomin idle and confusing to my mind, but that's what it is.
Might not help, but has been asked before: -

So, digging through a drawer to dig out an old work compass.
Looking at the mother of pearl disc; for normal nav, it's marked clockwise.
But, looking at the very outer ring on that disc, you'll see the numbers are anti-clockwise (and-not relevant, flipped, because they're read through the sighting prism/mirror)
This is so, when sighting, the compass tells you the bearing of what you're looking at.
On your watch, you would 'sight' by aiming the 00 at the thing you want to sight and the reading the value that the needle is pointing at. A bit 'oddly odd' in a non-prismatic, to my mind, but someone must have a use for the feature.

Thanks everyone, makes no sense but makes sense.👍😁
Point 00 towards your heading.
Hit the compass button. The needle will spin to point North.
The number the needle is pointing at is the bearing you're facing.
Think through an example. If you were facing a 30 degree bearing, and you triggers the compass to point north, where would the north facing needle end up on that bezel? On 30
This explains it well. I think they are called bearing compasses or similar (I know all compasses give you a bearing!) and are very handy if just navigating on a bearing, ie point and follow. Not as good for route planning or with maps, although obviously can still be used with both.Point 00 towards your heading.

Apologies if I’ve muddied the waters again!
Apologies can’t edit for some reason but thought I’d add a picture of my protrek
