Is the movement automatic or quartz?

It is a self-winding automatic with 20 jewels. It winds from wrist movement, so it stops if left unworn for a day or two.

No. Water resistance is 3 ATM, which covers rain and handwashing splashes but not swimming or showering.

About 44 mm across without the crown. That is a large case, so it wears big on smaller wrists.

What comes in the box?

The original Pionier box, a booklet or manual, a warranty card and a tag.

Is the gold plating solid gold?

No. It is 5-micron gold plating over 316L stainless steel, so the color can wear over years of daily use.

Yes, a date calendar sits on the skeleton dial alongside the diamond and Roman numeral markers.

Our take on the London Diamonds Pionier GM-510-7 Watch

The Pionier GM-510-7 is a gold-plated automatic dress watch with a skeletonized dial, a date calendar and diamond markers. Its 44 mm stainless steel case is plated in 5 microns of gold, and a 20-jewel automatic movement drives the open dial. It suits buyers who want an eye-catching gold watch with visible mechanics without paying for a Swiss luxury brand. Against plain-dial automatics at similar money, it offers more visual drama but weaker water resistance at 3 ATM and a busier face that some find hard to read.
