Orient Star Open Heart Tonneau DAAA004W or WZ0121DA (other options DAAA002T/WZ0131DA, DAAA003B/WZ0151DA & DAAA001W/WZ0141DA) – A Suave Timepiece, A Review (plus Video)

This is my first tonneau shaped wristwatch. The Orient Star Open Heart Tonneau with reference number DAAA004W (or WZ0121DA in Japan) has a vertical cross-section barrel shaped casing seldom used by watch manufacturers due to a number of reasons. It has the classical aura of a formal timepiece which I find very appealing. This particular model was released back in April 2014.

Age must be getting to me. During the start of my watch collection hobby I was keened on dive or sports watches. Formal or dress wristwatches were seldom in my radar. However, in recent times, my interest in dress watches started to grow and I have been shifting my focus towards that genre ever since.

The Orient Star Open Heart Tonneau is a stainless steel construction with polished and brushed surfaces. It has mirror finished top surface and a matte finished side. It has a curved sapphire crystal glass with anti-reflection coating protecting the dial and a flat crystal glass as a display case-back. The case-back panel is attached to the watch casing via four screws. The signed push-in crown is located at 3 o’clock and the watch comes with a power reserve complication. It is powered by an automatic engine that can be manually wound. The wristwatch is paired with a black matte calf leather strap with crocodile embossing and signed buckle.

Grand Seiko GMT Green Dial Spring Drive Limited Edition SBGE033 (SBGE033G) - An excellent timepiece, A Review and Video

My first watch purchase for 2016 is this Grand Seiko GMT Spring Drive Limited Edition SBGE033 which has a beautiful green dial. This watch was specially made in honour of the 55th anniversary of the Grand Seiko, the most famous premier line for the Seiko Watch Company.


Grand Seiko quietly released this sporty new GMT watch, the SBGE033 without the fanfare it had with the 62GS Historical Collection back in 2015. This subtle marketing strategy is very common with  Seiko. The Company believes it is unnecessary to promote an excellent product. The product will naturally promote itself, if it was designed and made to impress by its sheer effectiveness and quality.

I believe this is one of the only few sporty watches under the Grand Seiko line of watches (excluding dive watches). Granted there are a lot of GMT Grand Seikos but this is the only one with a contrasting chapter ring colour compared to the dial (white on green). It also has luminous hands and markers which are not seen before on its GMT watches.

Apart from the GMT hand, there are two other additional complications such as a date function in an aperture at 3 o'clock and power reserve indicator located near the 7 o'clock position.

It is powered by the in-house 9R66 caliber, the GMT version of the Seiko's Spring Drive Technology 9R65 movement. More about this later.

The case is made of stainless steel. With a 41 mm diameter case, the surface has been given a special hand finishing technique known as Zaratsu. Only 500 examples of this watch were made.
