Next, let us enter the formal watch evaluation session.

Appearance evaluation, full score 80 points, the score is as follows

Full score of 20 for positive appearance, score of 17

There is no problem with the whole front. For the blue plate, the color difference is a little bit. Especially reflected in the outer ring. Black has no color difference. Ye Mingzhu's control has improved slightly, a bit unsmooth, of course, I hope it's personality. The burr on the working edge of the entire pointer is still quite serious, and the hollow of the pointer axis is a bit big, which can be improved.

The oil pressure of the Longines logo on the dial is slightly lacking. In other words, there is no big problem with the details and appearance.

The appearance of the back is 15 points, 14 points

There is no substantial problem on the back of the whole watch, because it is a dense back cover, which is easy to make. It's nothing more than the logo on the details and the lettering on the edges are not so round and the depth and three-dimensional degree is not so perfect.Size and appearance full score 15 points, score 15

The size is 41×12, there is no problem with the size of the entire watch. Very easy to do.

The appearance of the strap is 10 points, 8 points

This time the strap only gave 8 points. The reason is that wherever it can be seen, its lettering is all shallow, which is obvious. Especially the logo lettering on the outside of the folding buckle.

Material appearance full score 10 points

There is no difference in the material of this product, because it is made of 316 steel, sapphire glass, and ceramic outer ring. This is a very conventional operation.

Function appearance full score 10 points, score 9

This time ZF uses a seagull 2824 white machine, and the counter uses the self-developed 1.888.2 movement. To put it bluntly, it is based on a 2892 basis for improvement. It can also be called eta exclusively for Longines movement. So they adjust the calendar in different directions, and of course it is not a big problem.

The internal evaluation score is 40 points, and the scores are as follows

Acoustic and vibration stable full score 10 points score 10

If you are interested in sound vibration, welcome to subscribe to us to watch the video, and there is also a meter adjustment tutorial for you to watch.

Fixed way stable full score 10 points score 9

The middle frame and case fixed with three screws and spacers are very good. But he used the middle frame to fix the movement with one edge.

Logically speaking, it is also very good, but he has installed two fewer screws to fix the movement. Although there is no major problem, it feels like cutting corners and just two screws.

The overall durability is 15 points, 13 points

I personally think that the Haigull’s white machine 2824 is very durable. Its durability is not less than 9015. It is also more durable than the rough Hangzhou 2836 and the Huaji Haigull 2824. Of course, it is a little bit different.

Use waterproof level of 5 points out of 5 points

The official rating is 300 meters waterproof, this product can support swimming, is a serious diving watch, but do not dive too deep if you snorkel

Movement perfect bonus +20 points (none)
