Extra bonus stainless steel band is enclosed in this package.
Sea-Gull 217.423 and 819.12.3002 are sisters.
The elder sister is wearing silver jewelry, and the younger
sister 217.423 is wearing gold jewelry (rose golden hands, hour markers,
bezel and crown vs. sliver).
This golden younger sister has radiant shining face vs.
silver elder sister’s creamy white face. Therefore golden 217.423 resembles
more closely to the style of European 1st tier brand. Have you got any idea
which brand does 217.423 look like?
Based on the prototype of ST21, additional features like
the moon phase at 2 o’clock, power reserve indicator at 10 o’clock, date
sub-dial at 6 o’clock make this watch appear more multi-functional and
complicated, while maintaining its advantage of 28800 high vibration per hour.
