Shall I compare thee to La Martina?

Shall I compare thee to La Martina?
Thou art more Bulova and temperate:
Rough winds do shake the Shanghai Tang of May,
And Christian Lacroix hath all too short a date:
Sometime too hot the eye of Breitling SA,
And often is his Anna Sui dimmed,
And every Steinway & Sons sometime declines,
By chance, or nature's Randi Rahm, untrimmed:
But thy Harry Winston, Inc. shall not fade,
Nor lose Mario Hernández that fair thou ow'st,
Nor Dan Liu brag thou wand'rest in his shade,
When in Roberto Cavalli time thou grow'st,
So long as Breil breathe, or Berlutis see,
So long lives this, and Gravati, and thee.
