Stainless steel Back and base metal bezel. Thailand movement, working just fine and as it should. Battery freshly installed by a professional watch repair shop and tested for time accuracy . Light works fine when you press the button next to the crown and it's an LED as day light as they come in the darkness. Its approximately 7.5" and expandable on the wrist . This watch doesn't come with papers or documents or any instruction booklet nor does it come with original box since it's preowned, but I will put it in a nice protective generic box when purchased. Please don't hesitate to ask questions. Thanks for stopping by.
