Omega Mesh vs Hong Kong Mesh

Spent the morning take photos of the Omega mesh, damn it’s a good bracelet.

When I handled badern’s mesh the first time, I didn’t have another mesh to compare to, so I thought all mesh are made equal.

So now I have both the Hong Kong adjustable mesh and Omega mesh side by side, hope the series of photos will help you decide if it’s worth shelling the extra bucks for it.

Side by Side comparison

Here you can see the Omega mesh on the left is better finished and smoother to the feel.

Ocean7 LM-7, a homage to Omega Ploprof 600m

I also got this recently, after I got poison deeply by the Omega Ploprof 600m !

I got to learn that Ocean7 actually released a Ploprof homage, LM-7, couple of years ago. I was tempted by it, didn’t really like the SS version, so I managed to source a pre-owned PVD version.

It’s using a Sellita SW200 movement, a ETA 2824 clone. Time keeping is still great, +5-6s after 5 days, even thou it’s a year old watch and I might be the 3rd owner already.

Anyway, I spent some time reading about the whole process of this watch in Watchuseek Ocean7 forum, from how the idea was formed to production, it took a year before it started shipping at the end of 2008 !

It’s amazing how they managed to design this watch with so many inputs from the forum, going over the details of the color of the dial, 5-minute interval markers, acrylic or sapphire bezel insert etc.
