VS New Seamaster 300m 42mm Dive Watch: 1. The new Seamaster 300 features a see-through case back (old model had a solid case back). 2. The new Seamaster 300 has been upgraded to a full ceramic dial identical to the genuine product (old model had a regular dial). 3. The markers and lettering on the upgraded ceramic bezel use white enamel, which is less prone to yellowing and has a glossy finish (old model was silver-gray). 4. The hands are larger and have a different shape than the old model, making the time easier to read. 5. The strap (mainly the end links) and clasp are different from the old model; the new Seamaster 300's clasp is adjustable.
